I was not able to locate the Vista disk....so many many thanks for this Info. I will follow the Repair instructions and get back to you.
WOW!! really appreciate it.
And thank you Donetao for all your valuable feedback as well
To answer your question, I haven't had a WU since 6/30/14 according to the log.
Eventhough, my pc goes thru the motions of downloading and installing every single day.
I recently tried to install Microsoft Power Point Viewer and got this error saying install failed.
When I researched via Microsoft it has something to do with Microsoft update, which is my current problem. There is a fix and I will try that first and
see if it solves the situation. If it works...certainly I will post it. If not...I will move on to Phills suggestion. Pls give me ample time to go through all these
steps. Thank you everyone!
