    The most common cause for this problem is the anti-virus software specially McAfee. McAffe removes a windows vista application required to install updates in error thinking it is a torjan. This applciation is known as wuauclt.exe. Go to the C:\windows\system32 folder and check whether wuauclt.exe is in this folder. If not download it from Microsoft. If you have the application, disable your antivirus software OR start your PC in clean boot mode and try to install.

    why would you have a 64 buit OS to begin with?

    Are you utilizing 64 bit software making Pixar movies?

    The only benefit is that you have unlimited memory??

    I would say to find the file erase/uninstall.

    And try again.
