Add-on won't install

I bought an add-on that I want to use with my Blender 2.93. However, only the link to 2.92 worked, so I downloaded my add-on and attempted to install it. Everything seems fine until it’s time to activate the add-on in the preferences menu. I end up getting this error. Can someone help me decypher what this means?

Update your Blender to 2.93.

Your error, cannot import name 'cache' from 'functools' comes from trying to import the ‘cache’ function from the ‘functools’ module, but this function was added recently (python 3.9), while Blender 2.92 still uses python 3.7.7.

I see, so bottom line, I can’t use the 2.92 version of the add-on with 2.93.

You’re using an addon that is supposed to work in Blender 2.93+, but you’re still using Blender 2.92!

Oh you’re right! Thanks for that!
