When I purchased the computer it did not have any installation disks. I went to a computer store that periodically does my repair and I asked him to make me a copy of Windows XP Professional for the purpose of installing a printer. I was not aware at the time that Office 10 which seems to inclued PROPLUS.MSI to run Excel was a separate Disc.
I have done another restore point back to when I used Excell last, but it didn't work this time.
I will attempt to purchase on line said disc as per your instructions. I just wanted to fill you in on the problem so others can read and understand problems that may arise.
Thanks for your help anyway.
