CADWorx SPLM Error 7502 is a common licensing issue that occurs when the software is unable to communicate with the SmartPlant License Manager (SPLM) server. This error typically stops your workflow by preventing CADWorx modules from launching, often displaying the message: "Could not read data from SPLM server".

The guide below provides a comprehensive walkthrough to diagnose and fix this error. Understanding Error 7502

At its core, Error 7502 signifies a broken connection between your local CADWorx installation and the license server. This can happen if:

The SPLM software is not installed or configured on the client machine.

Network issues are preventing the client from "seeing" the license server.

Firewall settings are blocking the specific communication ports used by Intergraph/Hexagon software. The CADWorx SPLM Error 7502 occurs when the

You are using an older version of SPLM that has been deprecated in favour of Intergraph Smart Licensing (ISL). Step-by-Step Solutions 1. Verify SPLM Client Configuration

The most frequent cause is that the local machine doesn't know where to look for the license.

Open the License Manager: Go to Start > Programs > CADWorx > License Manager.

Check Connection: Ensure the computer is configured to point to the correct SPLM server IP address or hostname.

Restart CADWorx: After making changes, fully restart the application to trigger a fresh license check. 2. Check Firewall and Network Access

If the configuration is correct but the error persists, your network may be blocking the "handshake" between the client and server.

Add Firewall Exceptions: Ensure pdlice.exe (usually located in C:\win32app\ingr\splm\bin) is allowed through the Windows Firewall.

Test Connectivity: Open a command prompt and try to ping the license server’s IP address. If the ping fails, you have a general network connectivity issue that must be resolved by your IT department. 3. Address Legacy Software Conflicts Step 4: The Windows Firewall Deep Dive (Port

Intergraph (Hexagon) has transitioned away from the traditional SPLM system.

Upgrade to Smart Licensing: As of December 31, 2024, Hexagon no longer generates new license keys for the old SPLM system. If your organization has migrated, you must install the Intergraph Smart Licensing (ISL) Client instead of the old SPLM client.

Clean Install: If you have both SPLM and ISL installed, they may conflict. It is often recommended to remove the old SPLM before installing the new Smart Licensing system. 4. Advanced Troubleshooting Intergraph Smart Licensing - Version 14.3 - Help - Hexagon

Step 4: The Windows Firewall Deep Dive (Port 2575)

SPLM typically uses TCP port 2575. However, some newer versions use random dynamic ports. Error 7502 frequently appears after a Windows security update resets the firewall.

On the License Server:

Open Windows Defender Firewall with Advanced Security.
Click Inbound Rules > New Rule > Port.
Select TCP > Specific local ports: Enter 2575.
Choose Allow the connection.
Apply to Domain, Private, Public.
Name it "SPLM Inbound".

On the Client PC:

You may need to allow outbound traffic on port 2575, though inbound rules on the server are usually sufficient. To be safe, temporarily disable the firewall on the client (for 30 seconds) to test if the 7502 error disappears. If it does, create an Outbound Rule allowing CADWorx.exe and SPLM.exe.

How to Prevent Error 7502 in the Future

Once you resolve the immediate issue, implement these best practices to ensure Error 7502 never returns.

Static IP for License Server: Never use DHCP for your license server. Give it a permanent IP address and static DNS entry.
Automated Service Recovery: In Windows Services, right-click SPLM License Server > Recovery. Set First Failure, Second Failure, and Subsequent Failures to Restart the Service.
Regular Backups: Back up the TrustedStorage.bin and your .lic license files monthly.
Version Locking: Do not update Windows Feature Releases (e.g., 22H2 to 23H2) without first checking SPLM compatibility.

5. Use the SPLM Monitor/Client Configuration

On the client machine, you may need to explicitly define where the license is located.

Search for SPLM License Setup or Client Setup in the Windows Start Menu under the Cadworx folder.
Ensure the License Server field is populated correctly.
- Try using the IP Address instead of the Server Name if DNS issues are suspected.
- Ensure the port is specified if required (e.g., 7447@192.168.1.50).

3. Check Your License File

Open C:\ProgramData\SPLEM\licenses\cadworx.lic (Note: ProgramData is hidden by default).

Ensure the file is not empty or corrupted.
Verify the hostname and MAC address match your server.

Example Troubleshooting Timeline (concise)

0–15 min: Check logs and ping license server.
15–45 min: Test port connectivity, review license file, restart license manager service.
45–90 min: Verify versions, adjust environment variables, check firewall.
90–180 min: Escalate to vendor with gathered logs, timestamps, and server/client environment details.

6. Contact your license administrator

Confirm that borrowing is enabled for your user/group.
Check server-side logs for borrowing failures.

If the problem persists after these steps, provide the exact full error message and your SPLM version — that will help narrow down the cause further.
