i have got only Revit 2020&2021 installed and the C:\ProgramData\Autodesk\ApplicationPlugins was not present
had to create it manually for addin manager to work otherwise got this error:
i guess this is legacy folder structure and its easy to omit.
probably the easiest way for addin would be to guard clause against presence of this folder and create it if necessary.
checked on versions 1.1.1, 1.1.2, 1.1.3
best regards
