Create an “ActionRecorder” folder under “(install folder/)blender/2.93/scripts/addons” and paste the uploaded files

Then (in windows 10) right-click the ActionRecorder folder Select Properties>Security tab>All Application Packages then Select Edit… and in the lower area check Allow in the Full Control line.

In the top area scroll down until you can Select the Users group and in the lower pane checkAllow” in the “Full Control” line.

Start up Blender from the command line AND

If everything worked navigate to the Edit>Preferences>Add-Ons menu then Select the All dropdown and select System. The ActionRecorder add-on should be listed AND

The command from window should show no permissions errors for the add-on.

Hope this helps, folks.
