Revit 2021 Add-in not showing up for one user

[kameron1967]

Hi,

I wonder if anyone's ever run into a situation where under one login, the user is not able to see the Revit add-in, but if logged in as someone else, you can see it and use it.  Any idea what could be the factor?

The addin path is the C:\ProgramData\Autodesk\Revit\Addins location.

Hi.

please compare the following Folder of the two Users. Is there an *.addin file in the Folders.
%AppData%\Autodesk\Revit\Addins\2021

[kameron1967]

Yes, the addin file exists and the command area points to the corresponding addin folder.

Close Revit and rename the Registry Key "Computer\HKEY_CURRENT_USER\SOFTWARE\Autodesk\Revit\Autodesk Revit 2021\CodeSigning" to "_OLD" and reopen Revit.

To you get a security message like this:

Maybe you also can show the content from the *.addin file. You can open in Notepad. In some case there is a problem when the Path to the DLL is not absolut. See path in  <Assembly>.....</Assembly>

Folder location is in C:\Program Files\Autodesk\Revit 2021\AddIns folder
