Can you run the system file checker to check for system file corruption - follow Option 1 in the folliwng link:

I had run this before on July 9 (message 3) but ran it again and now can't open the CBS.log file-access denied in Wordpad. I did find the original sfcdetails.txt from July 9, showing the info but not anything from July 13, don't know why as I'm running as the administrator.
I finally found the file checker info, hadn't used Notepad for awhile but found and saved the CBS.log file, over 9MB. I don't understand all that it's telling me and could include a snapshot of today's running of the SFC as a .jpg but don't know if it's possible to do so or is allowed. Anyway, the windows installer still fails.
After discovering that I could not do a manual restore point and newly installed programs were not added to the restore section, I decided to bite the bullet and do a clean install. Since then, all my gremlins are gone and all the re-installed programs and Windows updates have been working correctly, including restore points. No more VBScript errors or Java errors.
Thanks to all who offered their time and suggestions.
