Windows XP SP3 is not updating. Update downloads files but installation fails Error Code: 0x641. Microsoft Fix it will not run due the problem. My CD is a service pack 1 CD so when SCF /scannow runs it can not find the files to fix the problem. I tried to download SP3 but when running, I get an error message saying the exe is not a valid win32 exe.
I'm running into many roadblocks trying to fix this problem. Any solutions that do not include running Fix it since it will not run?
