I have a laptop with SP1 installed, winver confirms this. If I try to install SP2 I get an error saying that SP1 must me installed, attempting to install SP1 produces a message that SP1 is already installed. This same SP2 patch downloaded, not using Windows Update, installed correctly on my desktop. When I tried using Windows Update it ran for abour 30 seconds and stopped, when I checked for available updates SP2 was still on the list.

Any suggestions?

I thought I just read a blog about this the other day that said all the language packs must be uninstalled one at a time before installing SP2... I'll see if I can find the posting...

I downloaded the update pointed to by your message but when running it I get a message that the update isn't for this system.

I didn't apply any extra language packs either and my fdesktop installed SP2 without problem.

I sent a link for 32 bit. If you are running a 64 bit OS click here. Check to make sure your SP is for the correct version as well.

Ran chksur, never had installed another version of the SP sothe vlite key was not present, and tried selective startup.

checked for spyware, malware and the like? Try cleaning the registry with something like AML Free Registry Cleaner.

I regularly run Registry First Aid, and SpyBot S&D and ran them when this all started.

Do you have any idea what keys or files the SP is searching to determine if SP1 is installed?

I always wait a couple of weeks before installing any major Microsoft update such as a Service Pack or new version.

If for no other reason than the beta testing never finds all of the bugs.

Once the bugs with the update are known, then you can proceed to work past the bugs.

Another thing I have found to be almost a requirement on the last few service packs is to download the ISO file and burn a CD or DVD for the installer. That way, if the update breaks your Internet connection part way through, you can still complete the installation.

I'll wait and see if anyone else reports this one, and count myself lucky it went on on my main machine so smoothly. I did download the file, though I did not burn a CD, I am cautious about internet connections too even with broadband.
