original title: Updates KB2539636 KB2533523 KB2468871 my windows update has installed updates today august 10 2011. but these three dotnet updates (KB2539636 KB2533523 KB2468871) failed to install... can anyone help me please?? thank you... btw i am using windows 7 home premium

Thank you very much Ladislav. Manually it finaly worked!!!!

I did the same thing as you and was able to install all three upgrades without any problems! I've been trying to rectify this problem for 3 days, it had me stumped. My system is Windows 7 Home Primeum. Thanks Jerry and all you others.

Hi LC Thanks for the Vista link - will try it when I get more time this week. I tried Jerry_in_San_Diego's tip about uninstalling the UAC before trying installs, but it didn't work. Weirdly, 2539636, 2533523, 2468871 have now dropped off the available updates list and don't show in the update history list but do now show as installed updates. I still can't install 255632, 2536276 and 2559049, which all produce Code 80070005 error messages. Sometimes the update screen says "Windows is up to date" and sometimes it lists these three as outstanding.

Hi, you're right , but there were cases where only****off UAC did not help . Maybe I could put it there in the comments. LC

Windows Update fails to install updates KB2539636, KB2533523, and KB2468871.

...x64 - is for 64bit WIndows 7

...x86 - is for 32bit WIndows 7

How to find out if Windows 7 is 32bit or 64bit is here:

EDIT 8/26/2011

Maybe what you can try (before you try points 1..11) only turn Off your antivirus and turn Off UAC, then manually install the updates that failed to installand run Windows update to install rest of updates. Turn On your antivirus and turn On UAC. How turn Off UAC see point 5).

EDIT 8/16/2011

If these steps above not help, try to use these ones:

1) uninstall Net Framework 4.0 client from „Uninstall and change program“:

2) If you still see Net Framework 4.0 client in „Uninstall and change program“ use this tool for unistallation Net Framework 4.0 client:
