Updated a bit for clarity (or add to confusion).
The Security Update for Microsoft .NET Framework, Version 2.0 (KB917283)
continues to fail with MS Update/OneCare, with OneCare continuing to pop-up
updates required. The same situation occurs without OneCare installed.
It seems to be caused by (many) people never updated the framework 2.0
(FEB06) or reinstalled a SDK and MS seemingly has not caught it through
automatic updates.
Thus far the fix appears to be (10 sucessful updates):
1:Turn automatic updates off.
2: Download .NET 2.0 (for 32-Bit) at this link:
http://www.microsoft.com/downloads/...cb-4362-4b0d-8edd-aab15c5e04f5&displaylang=en
Note:Some ATI VGA users may need to disable/exit the Catalyst Control Center
(which uses .NET) before updating the framework. We ran into one machine that
had this situation.
OR
2a: Download .NET 2.0 (for 64-Bit) at this link:
http://www.microsoft.com/downloads/...00-ACF8-4FA1-AFFB-40E78D788B00&displaylang=en
We have not seen a problem with XP 64-Bit but for completeness...
3: Uninstall Microsoft .NET Framework, Version 2.0 and reboot.
4: Install Microsoft .NET Framework, Version 2.0 (for 32-bit: dotnetfx.exe
3/22/2006) or (for 64-bit: NetFx64.exe 3/30/2006) and reboot.
5: Then run MS Update (and install KB917283) then reboot.
6: Turn automatic updates on (assuming that is your preference).
This appears to clear up the situation. I hope this helps you.
