Issue:
I came across a problem while running our split beam tool. I don’t believe it was a problem with the tool but that has yet to be proven. I restarted my machine and when I started Revit I got this error message.
Solution:
Uninstall the VisionRez for Revit 201X. Verify that the C:\Program Files\ITW\ITW Revit Extensions 201X folder has been removed/deleted as well as C:\ProgramData\AlpineITW\VisionREZ201X
Re-install the VisionRez for Revit 201X application
