Mogurt Files still don't install - been a problem since 2018 it seems??

I have the latest Rush version. I have an Install Template button available to me. I select the Free Mogurt Files designed for Rush, found through the Creative Cloud. Nothing happens. I try all Mogurt files in the Bundle provided - nothing happens when I select them. I see this working in youtube tutorials, but perhaps prior to 2018??  Could this be fixed so we could have more than a few options? Thank you!
