Error installing import_vcap into blender

[worldwidepixel]

If I try to install the blender addon into any* version of blender (*of those I tested [2.91.2, 2.79b, 3.0.0] ), I get the error below:

Error shown when attempting to install:

  File "C:\Program Files\Blender Foundation\Blender 2.91\2.91\scripts\modules\addon_utils.py", line 351, in enable

EDIT: New day, new, and different (for some reason) error!

P.S. I don't use GitHub that often, and I have never submitted an error. Sorry if I've made a fool of myself!

My blender version was too old. That is all.

I did make a fool of myself!
