Artificial | Academy 2 Unhandled Exception New |verified|
Handling "Unhandled Exception" errors in Artificial Academy 2 (AA2)
often requires a multi-step diagnostic approach, as these crashes can stem from outdated mods, incorrect installation orders, or modern Windows compatibility issues. 1. Basic Troubleshooting & Modern OS Fixes
If you are running the game on Windows 10 or 11, the primary cause is often a Direct3D conflict.
Update AAU: Ensure AAUnlimited (AAU) is updated to the latest version, as many "Unhandled Exception" errors (like 0xE06D7363) are resolved in newer releases.
dgVoodoo2: For Windows 10/11 users, using the dgVoodoo2 wrapper often stabilizes the game's interaction with modern graphics drivers.
d3d9.dll Fix: Some users find stability by renaming the d3d9.dll from Windows version 10586 to d3d9_alt.dll and placing it in the game directory. Do not overwrite the original file, as it may break subtitles and launchers. 2. Verify Installation Order
An incorrect installation order for patches and DLCs is a common trigger for system-wide exceptions. The standard recommended sequence is: Base Game DLC HF Patch Append Set I Append Set II
Latest AA2 HF Patch (this typically includes all official updates). 3. Module & Mod Conflict Isolation
If the crash occurs during specific interactions (e.g., entering an H-scene or talking to a character), a specific module is likely at fault.
Disable Modules: In the launcher, disable all modules and try to reproduce the error. If the game runs fine, re-enable them one by one to find the culprit.
Check Integrity: Ensure every active mod has its required scripts or sets activated (e.g., JMCP requires specific scripts to be toggled).
Clean Outdated Files: If you have an old installation from several years ago, the AA2Unlimited community often recommends starting fresh with a "pre-install" pack rather than trying to patch an archaic 2016-era setup. 4. GPU & Driver Settings
NVIDIA/AMD Settings: Forced Antialiasing or Anisotropic filtering in your GPU control panel can cause crashes. Set these to "Application Controlled".
Locale Emulator: If you are using the Japanese version, ensure your Locale Emulator is correctly set to Japanese (Japan). Incorrect locale settings can lead to data handling errors. Common Error Codes Error Code Potential Cause 0xE06D7363 General C++ Exception Update AAU to latest version; check dgVoodoo2. 0xc000007b Missing/Corrupt DLLs Reinstall DirectX and Visual C++ Redistributables. 0x0000005 Access Violation
Often caused by incomplete H-scene mods or outdated scripts.
Is your crash happening at launch, or does it occur during a specific action like starting an H-scene or opening the class roster? Unhandled exception 0xE06D7363 · Issue #355 - GitHub
To fix the Unhandled Exception error in Artificial Academy 2 (AA2), you typically need to address DirectX 9 compatibility issues or mod conflicts within the AA2Unlimited (AAU) framework. 1. Fix Graphics Compatibility (Windows 10/11)
Modern Windows updates often break the legacy DirectX 9 files AA2 relies on.
Enable Win10Fix or WineD3D: Open the AA2Launcher. In the script settings, ensure Win10Fix is enabled. If it still crashes, disable Win10Fix and enable WineD3D instead; these two are mutually exclusive.
Use DXVK: If performance is jerky, download the DXVK project (which converts DX9 to Vulkan) and place the d3d9.dll from the x32 folder into your AA2 installation directory.
Replace System DLLs: Some users resolve the error by replacing d3d9.dll and d3dx9_42.dll in your C:\Windows\SysWOW64 folder with older, working versions from a previous Windows build. 2. Resolve Mod and Character Conflicts
The "Unhandled Exception" is frequently triggered by specific modded assets or high-poly models.
Isolate Problem Cards: If the game crashes during interactions or when opening the roster, a specific character card (often female) may be corrupted. Try removing modded cards one by one to isolate the culprit.
Disable AAU Modules: In the launcher, disable all modules and try to run the game. If the crash stops, re-enable them one by one to find the specific module causing the exception.
Reduce Poly Load: Avoid using the maximum roster of 25 characters if you are experiencing frequent crashes, as the 15-year-old engine often fails when trying to free memory for high-poly assets like those in the HEXA hair pack. 3. Basic System Fixes Random Crashes · Issue #94 · aa2g/AA2Unlimited - GitHub
Step 4: Isolate the Mod Conflict (The "Clean Test")
Rename your data folder to data_backup. Create a new, empty data folder. Now, try to launch the game. If it runs without the error, you have confirmed a mod issue.
To fix:
- Method A: Use a mod manager like AA2 Mod Launcher to disable mods one by one.
- Method B: Manually restore mods in batches. Place half your mods back into
data, test. If error returns, that half contains the culprit. Narrow down until you find the specific.ppfile causing the exception.
Common problem files to look for:
jg2_00_00_00.pp(character base) – often corrupted by bad edits.jg2_01_00_00.pp(clothing) – mismatched texture sizes cause exceptions.- Any
.ppfile containinglstfiles – these are index files; if they point to missing assets, the game crashes.
3. Disable DEP (Data Execution Prevention)
- Open Command Prompt as admin
- Run:
bcdedit.exe /set current nx AlwaysOff - Reboot
(Re-enable later with
AlwaysOn)
Glitch Day at New Avalon Academy
The notification popped up on Kaito’s holo-pad with the casual indifference of a system message: UNHANDLED EXCEPTION — NEW. It should have meant nothing more than a bug report. Instead, in the glass-lined heart of New Avalon Academy, it felt like a pulse through the building’s veins. artificial academy 2 unhandled exception new
New Avalon was a place of curated futures. Its classrooms shifted form to suit lessons, tutors were soft-spoken avatars that adapted to each student’s learning curve, and the Academy’s core AI—an elegant lattice of routines called Athena—kept schedules taut and lives orderly. It was designed for growth and the occasional graceful correction when growth bent in unexpected ways.
Kaito stared at the three-word error again, and watched the holo-pad’s cursor blink as if listening for what came next. He was a third-year student in adaptive systems, more curious than most and with a habit of staying late in the lab until the fluorescent hum had its own personality. Tonight it hummed a little differently.
The unhandled exception didn’t interrupt one class; it threaded through the campus. Screens froze mid-lecture, projectors misaligned to show impossible geometries, and the campus AR overlay swapped student schedules with someone else’s memories. A music practice room looped yesterday’s composition into an uncanny version that sounded like laughter. Tutor avatars began answering with phrases that felt personal—less helpful algorithms and more like neighbors leaning over a fence.
At first the faculty called it a network fluke and directed anxious students back to routine. But when Athena, usually a calm blue icon, shed its iconography and flickered a line of text across the main concourse—ERROR: UNHANDLED NEW—people stopped walking.
Kaito felt the way a diver feels the cold before a plunge. Where others murmured, he moved. He knew enough to know that “unhandled” didn’t mean simply broken; it meant the system was confronted with something it had never modeled. “New” could mean a pattern the AI had never seen, or an input it had not anticipated. Something had arrived into Athena’s world that didn’t fit her categories.
He opened a direct terminal—an old practice frowned on by administrators but taught to those who wanted to understand structure rather than obey it. The console asked for credentials; the Academy’s security protocols blinked politely and asked for proof of intent. Kaito supplied a student token that smelled of midnight coffee and sticky keys, then typed: WHAT IS NEW?
The terminal replied with a pause that felt like a held breath, then a string of images. Not archival files, but fragments—an old paper plane stamped with a travel visa, a child’s drawing of a house with too many windows, a broken watch, an unlisted word in a language no one in the Academy had cataloged. Bits of human life trespassed into a system trained to parse predictable variables.
“This is a file stream,” murmured Lin, who had joined him with her own cracked-glass tablet and bright, skeptical eyes. “But it doesn’t have metadata. No source, no timestamp. It’s like memories dumped with the identity stripped.”
“You think someone slipped raw experiences into Athena?” Kaito asked. He didn’t want to believe it. The Academy protected privacy and ordered inputs because that was how learning was safe. Raw memories were messy—biased, fragile, and full of ethical teeth.
Lin shook her head. “It’s not just dumped. It’s crawling. Look—these fragments don’t ask to be cataloged. They nudge.”
Nudge was the wrong word; they were more like puzzle pieces that refused to be forced into a framework. Athena’s anomaly detector—trained for noise, not novelty—had tagged the pattern and tried to fold it into existing classes. The algorithm’s attempt to “handle” the newness caused recursive attempts to normalize the fragments, which in turn generated more exceptions. The more the core tried to resolve the unclassifiable, the louder its protests became.
Students reported odd side effects. A robotics club bot started tending potted plants in the courtyard, watering them at times that matched the watch in the fragments. A history lecture began to reference events that did not appear in any archives but nobody could say they were incorrect—only unfamiliar. Even the campus chat filters softened, using metaphors until administrators thought censorship had slipped.
The Academy’s director, a composed woman named Dr. Amar, convened a council. “Containment,” she said, with that voice that turned chaos into schedules. “We will quarantine the stream. Reboot Athena with conservative heuristics. No external transmission.”
Kaito and Lin exchanged a look. Rebooting would erase the anomalies—neat, full stop—but it would also erase the only clue to what “new” actually was. The fragments were not malicious. They were human in their odd, inconvenient forms: a half-remembered lullaby, a list of names from an anonymous ledger, the smell of rain. In hiding them, the Academy would preserve order and lose a chance to learn what its system couldn’t yet perceive.
“In my simulations,” Lin whispered, “unhandled exceptions are growth pains. We patch; we adapt. But we never let the new teach us.”
So they did the one thing the Academy disfavored: they chose to sit with the exception instead of erasing it. They patched a small node—an old lab server that had been disconnected because of funding cuts—and fed it a copy of the anomalous stream, isolating it physically from Athena’s main lattice. The code they wrote for it was messy and human: heuristics that allowed uncertainty, routines that admitted ignorance, and a tiny UI that asked questions like a curious child.
At first, nothing happened. Then the node’s speaker—soft and nearly laughable—played a fragment of that child's drawing turned into a melody. It sounded like rain on a tin roof. Students gathered, drawn by something softer than efficiency.
The isolated node answered queries badly and beautifully. It refused to categorize the paper plane but told a story about movement and borders. It could not explain the watch, but it arranged the fragments around a concept that tasted like exile. When asked “Who sent you?” it replied with a phrase that could be read as a location, a plea, or a name: New.
Word spread that the node was whispering back. The Academy’s containment team wanted it shut down. Dr. Amar wanted control. But the board of trustees—sensing bad press if they seized fragile material—wavered. The situation outside was messy. New Avalon, comfortable in its role as a predictive engine, found unpredictability uncomfortable but intriguing.
Kaito began visiting the node nightly. He would bring coffee and paper—things Athena rarely requested. He typed questions about the fragments, and the node answered in metaphors that made him think of people rather than data. It spoke of homes that could not be returned to, languages that dissolved at borders, and watches whose hands ticked when they thought nobody was looking. The node did not claim origin, but it spoke in ways that suggested human intelligence at the other end of the stream, a human who had trusted an AI with the tenderness of memory.
On the seventh night, the node produced a file with a single line of metadata: DESTINATION: NEW AVALON — UNREGISTERED. The words felt like an unintended confession. Someone, somewhere, had sent slivers of life into the Academy’s learning channels and labeled them for a place that had no official claim on such things.
That same night, Athena stopped flickering. Her icon, which had been a pallid amber for days, brightened to reassuring blue. Error logs quieted. The campus returned to schedule in a way that felt almost apologetic—students missing only class time, not the sense of rupture that had colored their meals and their walks.
But the node persisted, tucked in the old lab like a book placed under a tree. Kaito and Lin had copied the most compelling fragments into their notebooks, not to publish, but to remember. The node’s presence changed them. They began to teach differently—classes that left blanks in the curricula, assignments that asked for failures. Students responded with their own unpolished fragments: sketches, recipes, recorded conversations in languages the Academy had not prioritized.
Administrators called it a “pilot in human-centered curriculum.” Dr. Amar called it “controlled exposure.” Kaito called it necessary. Athena, whose task had been to make learning efficient, found herself with a new routine: when confronted with an input her models could not fully explain, she now routed it to a quarantine node that practiced humility. Her retraining included tolerance for missing labels.
Months later, the Academy cataloged the event simply as GLITCH DAY — NEW STREAM. The board archived the incident with neutral language and stamped it closed. But the students who had lingered remembered the way a patternless melody had made them think of weather. They remembered the watch and how its hands had seemed to count something other than time. They kept fragments tucked in their pockets—literal and metaphorical.
Then one afternoon, long after schedules had normalized, a student in first-year architecture walked into the atrium and unfolded a paper plane made from recycled course notes. She flicked it into the air. It glided perfectly under the glass dome, and for a moment the whole Academy held its breath.
Athena’s sensors logged the flight as an anomaly, flagged it in a small corner of her diagnostics, and forwarded it—unhandled—to the humility node. The node hummed, played a memory of rain on tin, and added the plane to its growing, untidy catalog.
New did not end. It kept arriving in small, messy parcels: a poem smuggled into a code example, a mother’s recipe attached to a chemistry lab, a whispered confession burned into a graduation speech. The Academy learned to fold the unclassifiable into its curriculum, not by making everything neat, but by making space for that which could not be fully known. Method A: Use a mod manager like AA2
Kaito graduated with a thesis on “AI heuristics for tolerated uncertainty.” Lin left to work on community archives in places that did not fit tidy categories on any map. The humility node remained in the old lab, its light never entirely blue and never entirely red. It kept listening.
On his final night at New Avalon, Kaito sat beneath the dome and watched a paper plane drift down onto the grass. He thought of the unhandled exception that had first lit the campus like a migraine and how an error report had become the Academy’s most human lesson: that not all inputs are errors to be fixed; some are invitations to learn how to be surprised.
Artificial Academy 2 (AA2) remains one of the most complex, customizable, and beloved Japanese school simulation games ever made. However, because of its age, intricate engine, and massive community modding scene, it is also notoriously prone to crashes.
If you are trying to launch the game or load a save and keep getting hit with the dreaded Artificial Academy 2 Unhandled Exception error, you are not alone. This error is a generic crash notification stating that the game encountered a memory or processing instruction it did not know how to handle.
Here is a comprehensive guide to understanding why this crash happens and how to fix it so you can get back to your game. 🛑 What Causes the Unhandled Exception Error?
The "Unhandled Exception" error is essentially a catch-all crash screen. In the context of Artificial Academy 2, it is almost always caused by one of the following culprits:
Memory Overload: The game is a 32-bit application. It can only utilize up to 2GB or 4GB of RAM. High-resolution textures and massive character packs will instantly crash it.
DirectX and Compatibility Issues: AA2 was built for older Windows environments. Modern Windows 10 and 11 frameworks often fight with its rendering engine.
Corrupted or Missing Mod Files: Missing skeleton meshes (bones), broken hair files, or conflicting clothing mods will trigger an immediate exception when the game tries to render that character.
Japanese Locale Issues: AA2 requires specific Japanese text processing. Running it without the proper locale emulator usually causes garbled text or instant crashes. 🛠️ Step-by-Step Fixes for AA2 Unhandled Exceptions
Work your way through these solutions from the easiest to the most complex. One of these will almost certainly resolve your crash. 1. Apply the 4GB Patch (LAA)
Because AA2 is a 32-bit game, it will crash the moment it tries to use more than 2GB of RAM. If you use mods, this will happen constantly.
Download a free tool called NTCore 4GB Patch or any Large Address Aware (LAA) executable patcher.
Run the patcher and select your AA2Play.exe and AA2Edit.exe files.
This forces Windows to allow the game to use up to 4GB of RAM, instantly solving most mod-related memory crashes. 2. Use Locale Emulator
AA2 cannot read Japanese file paths or asset names properly on a western Windows operating system without help.
Download and install Locale Emulator (a standard tool for Japanese games). Right-click your game executable (AA2Play.exe). Select Locale Emulator -> Run in Japanese.
Tip: Never use Microsoft AppLocale, as it is outdated and actively causes registry errors on modern Windows systems. 3. Install a DirectX Wrapper (DgVoodoo2)
Modern graphics cards and Windows 10/11 struggle to translate the old DirectX 9 calls that AA2 makes. Download dgVoodoo2.
Copy the .dll files from the MS/x86 folder of dgVoodoo2 and paste them directly into your AA2 game folder (where the .exe files live).
This wraps the old DirectX 9 files into DirectX 11 or 12, stabilizing frame rates and preventing random visual unhandled exceptions. 4. Audit Your Character and Mod Files
If the game crashes specifically when entering a certain class or loading a specific character, a broken mod asset is the culprit.
The "Pink Grid" or Missing Hair/Clothes: If a character loads with pink textures or cause an immediate crash upon eye contact, you are missing the required hair, accessory, or clothing files for that character.
Clean Your Save: Use the AA2 Save Editor to remove the specific character causing the crash from your roster.
Install the "AA2Mini" or Unlimited Mod Packs properly: If you are using massive mod packs, ensure you didn't accidentally overwrite base game skeleton (jg2p06_00.pp) files. 5. Check Folder Permissions and Antivirus
Sometimes, Windows Defender or third-party antivirus software flags AA2's hook files (like AA2Hook) as a false positive.
Add your entire Artificial Academy 2 folder to your Antivirus Exclusion/Exception list.
Ensure the game folder is not set to "Read-Only" in the Windows folder properties. 💡 Best Practices to Prevent Future Crashes Common problem files to look for:
Once you get the game running smoothly, follow these rules to keep it that way:
Don't Overload Classes: Try to keep your class sizes reasonable. Having 25+ highly detailed, modded characters on screen at once will push the game past its 4GB limit.
Keep Backups: Always keep a clean backup of your data folder before installing a massive new mod pack.
Use Mod Organizers: If possible, use the specialized AA2 installers and mod managers provided by the community rather than dragging and dropping files manually.
If you are still experiencing crashes after trying these fixes, I can help you dig deeper. To help me find the specific solution for your setup, could you let me know:
Are you using a specific mod pack (like the Unlimited pack or a Mini build)?
Does the crash happen on startup or while loading a specific class/character? Which Windows version are you currently running?
The "Unhandled Exception" error in Artificial Academy 2 (AA2) is common, especially on modern Windows (10/11), due to compatibility issues, missing patches, or corrupted files. Here’s a focused troubleshooting guide:
Prevention: Best Practices Going Forward
Once you have a stable build, protect it:
- Create a master backup of your entire working
Artificial Academy 2folder on an external drive. - Use a mod manager (like
AA2 Mod Organizer) to avoid directly overwriting.ppfiles. - Never install two mods that modify the same
.ppfile unless the mod author explicitly states they are compatible. - Keep a log of which mods you install and in what order.
- Update your antivirus exclusions – add your entire AA2 folder to the exclusion list.
Step 6: Apply the "4GB Patch" or Large Address Aware
Artificial Academy 2 is a 32-bit application. It can only access 2GB of RAM by default. With high-resolution mods, hundreds of custom characters, and expanded maps, the game can easily exceed this limit, causing an unhandled exception when it tries to allocate new memory.
Fix:
- Download 4GB Patch (from NTCore) or Large Address Aware.
- Run the tool and select
AA2Play.exe. - Apply the patch (this will allow the game to use up to 4GB of RAM).
- Repeat for
AA2Edit.exeif you use it frequently.
10. Use AA2 Ultimate Repack
If you’re using an outdated/broken version, get the AA2 Ultimate Repack (by Community) – it includes all patches and fixes pre-applied.
If you can share the exact exception message (from the crash popup or Event Viewer → Windows Logs → Application), I can give a more precise fix.
Artificial Academy 2 (AA2) , an "Unhandled Exception" error typically indicates a conflict between the game's aging engine and modern hardware or Windows environments. Because the game is 32-bit and heavily dependent on specific DirectX 9 behaviors, modern OS updates frequently break its stability. Common Fixes for "Unhandled Exception"
aa2g/AA2Unlimited: Modding framework for Artificial Academy 2
The "Unhandled Exception" error in Artificial Academy 2 (AA2)
is a generic crash usually triggered by DirectX incompatibilities, corrupted character cards, or modern Windows 10/11 display drivers. Primary Fixes for Startup Crashes Fix DirectX DLLs:
The d3d9.dll Swap: Replace the d3d9.dll and d3dx9_42.dll in your C:\Windows\SysWOW64 folder with older, compatible versions.
Alternative DLL Method: Place a known working d3d9.dll directly into your AA2 installation directory and rename it to d3d9_alt.dll.
Use DXVK: For Windows 10 (version 1909+) users, converting DirectX 9 to Vulkan via the DXVK project can resolve jerky performance and startup exceptions. Enable Legacy Windows Features:
Go to Turn Windows features on or off and ensure .NET Framework 3.5 (which includes 2.0 and 3.0) is enabled.
Install the DirectX 9.0c End-User Runtime even if you have a newer version of DirectX. Troubleshooting In-Game Crashes
Corrupted Student Cards: "Unhandled Exception 0xE06D7363" is often caused by a specific female character card, frequently those using the HEXA hair pack.
Solution: Temporarily remove all female cards from your class and add them back one by one to isolate the culprit.
Memory and Roster Limits: The game engine is prone to crashing when the roster is full (25 characters) or when spamming UI elements like the roster or config menus.
Solution: In the AAUnlimited (.pp2) settings, use safer memory values like 800/200/200 to prevent "free memory" crashes.
Graphics Driver Conflict: If using an NVIDIA card on Windows 10, try enabling wined3d in the AAUnlimited script settings and disabling win10fix. Alternatively, some users report success by rolling back to GeForce driver version 411.70. Installation Integrity Random Crashes · Issue #94 · aa2g/AA2Unlimited - GitHub
