Windows Vista16
I am presuming my latest problem is due to a Windows Update, but I can't be

sure. On Nov 28 2007, my Windows Explorer (NOT Internet Explorer) stopped

working. I can't open folders nor run certain programs. I cannot open

anything to get to a previous restore point, nor can I check for Windows

Updates. When I try to open folders I get an error windows displayed as

Explorer.EXE in the header, and Class not registered in the body. The only

other thing in the window is the OK button. If I try to do a Windows Update

(I can only get to it through the internet, not through navigating my

computer) I get the following error: C:\Windows\system32\ExplorerFrame.dll

is either not designed to run on Windows or it contains an error. Try

installing the program again using the original installation media or contact

your system administrator or the software vendor for support. (Huh?) When I

close that window, another one pops up that displays the following:

::{21EC2020-3AEA-1069-A2DD-08002B30309D}\::{36EEF7DB-88AD-4E81-AD49-oE313F0C35F8}

Class not registered. (Whew!) Does anyone have the slightest clue what is

going on and how I fix this? Any thoughts and easy solutions/instructions

would be appreciated. I am running Vista Home Premium that came installed on

a new Dell XPS system.

What happens when you click on Vista Start button and type either "Restore"

or "rstrui" within the Start Search box ?



Do you get the same error ?



If yes, have you tried to run System Restore in Safe mode ?

I tried all the same things while in Safe Mode, but get the same error. Nice

try, though! I poked around in some other ways and got a bit further on

getting into some other folders that I was sort of locked out of, but the

more serious problem remains. Keep sending ideas if you have any. Thanks so

much.

I took my computer in to work to have a "real IT" person look at it. It was

beyond his ability to repair, so we went with reinstalling Windows Vista Home

Premium. He seemed to think that the error was related to a conflict between

Vista and my Norton anti-virus software.



After reinstalling Vista (I broke down and bought an external hard drive to

back up as much as I could beforehand), I then loaded all the Windows

Updates, then one by one added my software, including Norton Antivirus 2007.

It's been a week, and so far, so good.



I don't consider reinstalling Vista any sort of real solution - just a last

resort. Sorry I could not offer any better suggestions. Good luck!
