I found one solution on a different forum and have sent it on to several people with favorable results.
Go to Windows folder - find system32 - find catroot2 - rename catroot2 to catroot2old or any other name Windows will not recognize
Try your install again assuming that you have downloaded the updates.
This worked for 3 of the 4 updates mentioned in the previouse post.
Hope everything works as well for all.
Good luck
