Failed to initialize the add-in ...

[Marcus.Isacsson]

Hi fellas!

I recently uninstalled a plugin using the add/remove software in Windows.
But afterwards I've had an error saying "Failed to initialize the add-in ...".
How can I remove it manually?

Hi! Remove this .addin from C:\ProgramData\Autodesk\Revit\Addins\ or %UserProfile%\AppData\Roaming\Autodesk\Revit\Addins.
