In system upgrade won't run, report it can not install 64 bit on 32bit

In system upgrade won't run, it report it can not install 64 bit on 32bit and vice versa.
I know 100% it is a win7 pro x64 version and computer properties also claims this.
The history is that a week ago I notice most updates has fails since 17 june 2011,
But now I get notificed! I tryed to download these MS update fixes, I tried to clean update history etc. But update keeps failing. I read Binck turial 3413 about using in system upgrade to repair, I have the original install DVD. But the upgrade reports I cannot install 64 bit on 32 bit and vice versa, actually both message in the x64 try.
I tryed disable all non MS services using msconfig including my NOD32 antivirus doing the in system upgrade. I have loads of programs it will take many hours to reinstall and configur all programs to put data on a separate partion as I require.
All my tryes have made it crash when I should go into sleep, but I can still do a normal boot. Should I try in save mode?
Any other way ?
