Unfortunately, the Revit 2021.1.2 Hotfix does not include a fix for this issue because we have not been able to identify the root of the problem. If you have encountered this issue, the best course of action is to contact Autodesk product support, log an official case, and they will work to collect the necessary data to assist in our troubleshooting efforts.
We have found that the unexpected loss of license occurs after running particular commands that display a Windows file selection dialog. To date, Load Family, Load PDF, and Import CAD are the most common commands that lead to the license loss.
In addition to contacting product support, here are a few questions that may help us in our troubleshooting efforts:
- When this license loss occurs, dismiss the message and review the list of shortcuts in the left column of the Windows file selection dialog that is displayed. By default, Windows includes the following shortcuts: History, Documents, My Computer, My Network Places, Favorites, Desktop, Imperial Library, and Metric Library. Are there any custom shortcuts is your scenario and if so, we do these shortcuts point to? Does removing custom shortcuts resolve the license loss issue?
- When this license loss occurs, dismiss the message and make note of the default location in this dialog. Is the default location on the local hard drive or on a network drive? If the default location is on a network drive, please try browsing on a location on your local hard drive, select a file from there, and complete the command. After this exit the Revit session, launch a new Revit session, and run the same command. Do these action lead to the loss of license?
- What add-ons, plug-ins, or third party apps are installed for Revit 2021?
