Important Note: Mastercam X7 is legacy software (circa 2013). Error 39 usually means the HASP/Sentinel driver (the virtual USB bus that hosts the network license) failed to start due to driver signature enforcement or a corrupted installation.

2) Disable Driver Signature Enforcement temporarily (if driver is unsigned)

1. Open Settings → Recovery → Advanced startup → Restart now.
2. Troubleshoot → Advanced options → Startup Settings → Restart.
3. Press the option to disable driver signature enforcement.
4. After boot, reinstall the license driver (as admin). Re-enable enforcement by restarting normally.

Why does this happen after an update?

1. Windows Security Updates (Especially KB5028185, KB5030211): Microsoft has aggressively patched vulnerable drivers. Older Mastercam drivers (pre-2021) are often flagged as "vulnerable" or "unsigned."

2. Driver Signature Enforcement (DSE): Starting with Windows 10 22H2 and Windows 11 23H2+, Microsoft requires all kernel drivers to be digitally signed by Microsoft. The Aladdin/SafeNet HASP drivers for Mastercam X7 (circa 2013) are not.

3. CodeMeter vs. HASP Conflict: If you installed Mastercam 2022 (CodeMeter licensing) after uninstalling Mastercam X7 (HASP licensing), remnants of both systems fight over the USB bus.

4. Corrupt Driver Store: Windows Update sometimes deletes the hardlock.sys or aksfridge.sys files during a feature update. Mastercam X7 2022 Virtual USB Bus Error 39

Key Insight: The dongle is physically fine. Your USB port is fine. The communication bridge (driver) is broken.

Safety & Security Concerns

Rating: 2/5 (Caution Required) This is the biggest caveat. Because this fix modifies low-level system drivers to bypass licensing, it inherently looks like a virus to Windows Defender and other antivirus suites.

• False Positives: You will almost certainly have to add an exclusion for this file in your antivirus.
• Source Matters: Because this is not an official CNC Software Inc. release, the file is often distributed via forums or file-sharing sites. There is a genuine risk of malware being bundled with the batch file. Users must verify the MD5 checksum or download from a reputable forum community.

Part 6: Prevention (Avoid Error 39 Returning)

Once you fix the error, lock it down:

1. Pause Windows Updates for 28 days. Review each driver update manually.
2. Block HASP driver updates using the wushowhide.diagcab tool (Microsoft's "Show or hide updates" troubleshooter).
3. Backup your driver: After a successful fix, export the driver:
   • Device Manager → Mastercam Virtual USB Bus → Properties → Driver → Driver Details.
   • Copy all .sys files (e.g., hardlock.sys, aksdf.sys) to a safe folder.
4. Use a powered USB hub. Some motherboard USB controllers drop power during sleep, triggering Error 39 on resume. A powered hub maintains constant voltage.

Temporary Bypass (One Boot):

1. Hold Shift and click Restart from the Start menu.
2. Go to Troubleshoot > Advanced Options > Startup Settings.
3. Click Restart, then press 7 or F7 for “Disable driver signature enforcement.”
4. Log into Windows and install the HASP driver from Method 1. Mastercam X7 will work until the next reboot.

9. Final Verdict: Is Your Dongle Dead?

If you have tried all four methods above—including the updated universal driver, hidden device cleanup, and driver signature bypass—and you still see Virtual USB Bus Error 39, you may be facing hardware failure.

Hardware failure signs:

• Dongle LED is off or randomly blinks.
• Error 39 appears on three different computers.
• Mastercam X7/2022 works for 5-10 minutes, then crashes with Error 39 (overheating inside the dongle).

What to do:

• For Mastercam X7: The dongle is irreplaceable. You must upgrade your license to a modern NetHASP or software ID.
• For Mastercam 2022: Contact your reseller (e.g., In-House Solutions, MLC CAD Systems) for a replacement key under your maintenance plan.

For Windows 10/11:

1. Hold Shift and click Restart (from Start menu).
2. After reboot → Troubleshoot → Advanced Options → Startup Settings → Restart.
3. Press 7 or F7 for Disable driver signature enforcement.
4. Windows boots → try Mastercam X7 again.

If this works, you must repeat every reboot. For permanent fix, see Step 6.
