If you are using more than one Autodesk SSO, you may come across this problem…
- After a Windows Update or something similar, Revit is not responsive after first launch. Clicking has no effect, but there is no dialog shown either.
- You may investigate the process details and determine that LMU.exe is thrashing, and you could look at log file in C:ProgramDataFLEXnet and see it growing. You can also observe something like this in the Revit Journal file:
‘C 08-Aug-2017 14:53:49.479; 0:< manage licensing

‘C 08-Aug-2017 14:54:03.845; 0:< License cleanup skipped
