Issue: Procad crash when communicating with licensing server – Hotfix

Has your product been crashing when communicating with the licensing server? If so we’ve outlined below the solution to your problem.


Product users of version 2018 Autodesk single-user subscriptions may experience an intermittent crash. The crash occurs when it has been more than 24 hours since the last successful authorization check and there is intermittent or no internet connection, or the licensing authorization server is unavailable. The licensing authorization check occurs in the background and is completely unrelated to activities the user is performing at the time of the crash.
A fatal error  message may be shown by the product. For example:

FATAL ERROR: Unhandled e06d7363h Exception at ee563c58h

The error will likely be followed by a dialog requesting to submit the error report.

This affects all users of 2018 product versions on subscription with single-user access, on both Windows and Mac.
