I have experienced the same problem as you. I followed all of the instructions from Microsoft and still no luck. This is the first time I have had any trouble with updates. My Vista HP has run great since buying my new system in Feb. I'll keep looking into the issue and post back with any solutions. Maybe some of the great folks here have got some ideas. ?????? CK

"but there is no service pack 1 for vista"

 

It is a Service pack for Net Framework, not the OS.

 

 

Dave, What is the update number?  KB?

I've had the same problem with that update.  There is a lot on the web about that and even a Microsoft KB article.  I've tried everything listed on the Microsoft KB article and the various web sites and nothing works.  I currently have that update "hidden".  KB886903

I had the same failure. Tried the recommended solutions (deleting files and folders under the SoftwareDistribution folder) but to no avail. I then manually downloaded Service Pack 1 from here , saved it and installed. Worked fine. Subsequent to this installation, Windows update then recommended and installed a further Security Update for .NET Framework, Version 1.1 Service Pack 1 ( KB929729). This latter update was originally released in July but it was revised in late October.

Tried the manual download and it wouldn't install.  One other items was to uninstall Net Framework 1.1 and then reinstall, but Vista would not let me uninstall it (running as Administrator)

Strange............... I've followed this procedure on 2 machines now and it worked both times. I'm not sure what to suggest next???

Getting same message as you. After trying all suggestions listed in knowledge base with no different results, decided to submit trouble ticket to Microsoft on this issue. Able to do other updates so there must be an issue with the service pack 1 update. Hopefully I hear back soon from MS and will let you know what they say. Regards, George

Hey guys...I too have the same issue with the update.  I tried everything suggested and still can't get it to work.  If anyone comes up with a solution please post back on this thread.  Thanks.
