Parallels Tools hung up during upgrade and now I can't access \\Mac\Home\Desktop

I've tried everything from many articles in these forums:
- running the registration fix
- clicking and unclicking the many configuration options to restart
- Uninstalling and reinstalling Tools (FROM THE MAC SIDE ONLY)

Tools hasn't recognized as being installed on the Windows side since I restarted after the hang up.

What can I do?

 

Writing that question made me realize that I should try this and it worked:
