Windows installer can't install pure 64 bit software but works with 32 bit in compat

Hi, when I try to install a "real" 64 bit program, my system blue screens and bombs. I can install programs that are internally 32 bit but been emended to work in a 64 bit environment. One example of a program that won't install at all is iTunes 9.0.3...message comes up that the installer is not working. I had installed the previous version, 9.0.25 with no problem. Both are native 64 bit.
In some other cases, the system just crashes.

How do I download a new 64 bit installer or fix the one I have? At one time, I could install 64 bit...something must have become corrupted.

Many thanks for your assistance.

hello
try running the sfc /scannow, to repair corrupt/bad files....worth a shot...

start > type cmd in the search box, right click "command prompt" in the menu....and choose "run as administrator"
type sfc /scannow press enter.... (note the space between sfc and /scannow)

should give an option to repair files it finds that are bad....good luck

ps if it finds files and can't repair, run it again
