Autodesk Revit 2019 Licensing Error

Vague Licensing Error in Revit 2019


Last week, I received the most vague licensing error in Revit 2019. I was presented with the error message above which states nothing more than “Licensing Error” with no error code or description of the issue. I did a bit of Googling and couldn’t find a surefire solution to fix this. I did, however, learn that this issue plagues other Autodesk software such as AutoCAD.

I eventually reached out to Autodesk customer service and they provided these simple instruction to fix the issue:

  1. Navigate to %localappdata%\Autodesk\Web Services in your Windows Explorer.
  2. Delete the file named loginstate.xml

That’s it! This fixed my issue without the need to run updates, reinstall, or go through any of the troubleshooting that I found on the Autodesk Knowledge Network. Hope this helps!
