MVC 3 RTM Install Error (after upgrading to VS2010 SP1)

I have problem installing SP1 as well as MVC 3 RTM.

Following is the kind of error which I was getting in installation.

Action: Performing Action on Exe at k:\temp\ext27692\VS10-KB2483190-x86.exe…

[6/18/2011, 16:23:41]Launching CreateProcess with command line = VS10-KB2483190-x86.exe /q /norestart

Verify that the program to be upgraded exists on your computer and that you have the correct upgrade. .
[6/18/2011, 16:23:46]PerformOperation on exe returned exit code 1642 (translates to HRESULT = 0x8007066a)

 

For Resolutions:

I repair/reinstall VS 2010 so that I can install VS2010 SP1.

For MVC, I followed following article:-
