Error when opening Revit after pyRevit installation

[Jean-Marc (Jean-Marc Couffin)]

Hi, Sorry for the canned answer, but this is a common case: addins incompatbilities

1. Uninstall pyRevit

   2. Delete C:\ProgramData and %AppData%\ pyRevit and pyrevit-master folders

   3. Move all Revit addins to a temporary location. Usual addins locations include:

      • %AppData%\Autodesk\Revit\Addins
      • %AppData%\Autodesk\ApplicationPlugins
      • %ProgramData%\Autodesk\Revit\Addins
      • %ProgramData%\Autodesk\ApplicationPlugins

   4. [Reboot computer]

   5. Reinstall pyRevit

   6. Started each version of Revit confirming pyRevit successfully compiled at startup.

   7. Move all Revit addins that were moved in step 3 back to their original location.
      You may want to add them one at a time and start a revit session everytime to figure out which ones are causing the issue.
