add-in succesfully installed but it is not visible
I installed Revit 2019 and 2017 and installed the add-in successfully, but I don’t see the add-in where I think it should be (between Add-in and Modify tab or under Add-in tab). I tested different options – with folder, without folder, with other files from the download package, but nothing worked. I made several screen shots. Thank you for your help. Jasmina
