Zero Hour error

[Stamper]

Hi,
When trying to install this game i always get an error at the point where it pops up the window to enter the cd key. I get a windows error saying it was unable to execute this file:

Command and Conquer Generals Zero Hour_code.exe

I'm guesing maybe the image file i have is corrupt, but it could be a problem with my computer or something. Can anyone help me out here? Even if someone could post their version of the file listed above that would help greatly. Thanks.
