To solve the problem, one must first identify the likely culprit. Error 7502 usually stems from one of three areas:
The is almost never a CADWorx software bug. In 95% of cases, it is a Windows, network, or configuration issue. By methodically working through the steps above—starting with the ping test, checking the SPLM service, adjusting environment variables, and finally clearing the Trusted Storage—you can restore your license connection within 15 minutes.
: Ensure your machine can "ping" the license server. Firewalls or VPN issues often block the communication required for the SPLM seat .
If all available project licenses are currently checked out by other engineers, or if the client configuration environment variables point to an inactive or non-existent license group, the application drops the connection.

Troubleshooting CADWorx SPLM Error 7502: Causes and Solutions
Are you encountering this error on a or a network server environment ? To solve the problem, one must first identify
The license file tells SPLM which products you're allowed to use. If this file is missing, corrupted, or contains incorrect information (like an invalid HostID), the license server will deny the request for a license, leading to error 7502. The HostID in the license file must match your computer's physical MAC address.
Ensure remote workers use a VPN profile that permits UDP/TCP broadcasting across the corporate network subnet where the license server resides.
It often presents with a message similar to: If all available project licenses are currently checked
Set a weekly scheduled task on the license server to restart the SPLM service during off-peak hours to clear memory leaks.
The client machine is operating on a different subnet or a VPN that restricts UDP/TCP traffic to the server.
, ensure Hyper-V settings aren't blocking the license file transfer. 5. Re-seat the License (Checkout/Check-in) Sometimes the license gets "stuck." Use the SPLM utility to the license and then a fresh one.
