System32\dssenh.dll is not designed to run on this computer or has an error...

I have downloaded the latest version of itunes 10.6.3 and when I go to open it I receive a error C:\Windows\system32\dssenh.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

I have installed, uninstalled and re-installed with no luck. I appreciated any help you might be able to offer.

Thank you in advance.

iPod nano, Windows Vista

Taken at face value, you're having trouble with one of the Windows OS dlls associated with Cryptographic Services.

I'd first try the fixit from the following Microsoft document. (One of the things it does is reregister your copy of the dssenh.dll file.)

You cannot install some updates or programs

... but if you still get the issue, I'd try an sfc /scannow as per the instructions in the following document:
