Open a command prompt and run pyrevit attached
Take a look the ==> Attachments section. It should look similar to this. It should show that master is attached to all your installed Revit versions. The report looks similar to this:
==> Attachments
master | Product: "2020.1 Update" | Engine: IPY2712 (2712) | Path: "....."
master | Product: "2019.2.2 Hotfix" | Engine: IPY2712 (2712) | Path: "....."
If nothing is listed then run pyrevit clones and check to make sure master is listed as the installed clone
==> Registered Clones (full git repos)
==> Registered Clones (deployed from archive/image)
master | Deploy: "basepublic" | Version: "4.8.5" | Path: "......"
If it is listed, then run pyrevit attach master default --installed and check again to make sure it is attached.
If it is not listed, then find the installed pyRevit path (default is %APPDATA%/pyRevit-Master ) and manually register the master clone by running pyrevit clones add master <installed path>. Then check pyrevit clones to make sure it is registered. Now you can attach it using the command in previous step.
