Thank you. Yes I did that without success. I did find out what the problem was (an uninstall had partially failed and the photo program "wasn't there" but still worked!
During the process I tried to change the name of Paint (without success) to get it out of the way. I get the "you can't without the Trusted installer.... I admit that I don't know anything about the TrustedInstaller
If there is a way to remove paint, I would like to know how,but the issue is "solved" as far as the problem. Now curiosity is all that remains.
Thank you for your contact
