Essexboy-too late!
I have already done a clean install, just catching up getting things back to where I want them, but I will treasure that zip file for next time

I tried a repair install but no help, problem persisted.
I had Daemon Tools installed and that is probably the source of the problem according to my research and my logs. It seems to interfere with some registry files, hopefully, the Windows emulator will not cause a problem as I store a lot of my backups as iso files, and I like to have access to them without burning.
I guess that I got a clean install of my graphic drivers this time!!!!
Thank you for the help
Richard
