...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:

http://windows.microsoft.com/en-US/windows7/find-out-32-or-64-bit

 

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 install and  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“:

    http://windows.microsoft.com/en-US/windows7/Uninstall-or-change-a-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:

    http://blogs.msdn.com/b/astebner/archive/2008/08/28/8904493.aspx

    download, unpack and run „cleanup_tool.exe“ – from pull-down menu choose „.NET Framework 4“ and click „Cleanup Now

3) After uninstallation restart computer

4) Turn Off (Disable) your antivirus

5) Turn Off UAC (User Account Control) – howto do it:

     http://windows.microsoft.com/en-US/windows7/Turn-User-Account-Control-on-or-off

6) Download and install Net Framework 4.0 from here (choose right language):

     http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=17718

      (same for 32bit OS and 64bit OS)

7) restart computer

8) try to install manually all updates (KB??????) that failed to install

9) run Windows update and install rest of updates

10) Turn On UAC (User Account Control) – howto do it:

        http://windows.microsoft.com/en-US/windows7/Turn-User-Account-Control-on-or-off

11) Turn On (Enable) your antivirus
