Extension Manager CC won't install a plugin

I'm trying to install an updated version of Roland CutStudio, however, when I open it to install Extension Manager gives the error that it cannot be install because I have the wrong version of Illustrator

I have Illustrator version 22.1, so I do have the correct version.

I'm not sure why I'm getting this error or how to work around it?

Edit: I understand why this is happening, extension manager won't recognize illustrator. I've uninstalled Extension manager in hopes that reinstalling it would help it relocate the CC files. However, now I can't install Extension Manager. It says the install has failed.
