Ty,
I eventually found out that I had some application that MS Win 11 does not agree with which uses ZIP files and has ZIP files associated with it.
I also know that PowerDesk had been associated with zip files and I really liked it but the new Win 11 MS install screwed that up so now PowerDesk was preventing me from using it because I had "used up my installations" under the licensing agreement.
The only thing I found that I could do was remove PowerDesk. That solved the problem.
But the real problem is Microsoft programming. This should not happen to a mature OS!
Thank you Microsoft. That is the last time accept another one of your craxxy upgrades. You can't leave anything alone... years of use and familiarity and you just arbitrarily decide to change it.
Microsoft you have lost my support and trust.
