Are you sure it is not for HOI2?
 
So let me get this right.

You installed the game without any trouble.
Then you downloaded an HOI1 patch, and it asked you to enter a product code.

Where did you download this patch from please give me the link.
 
The problem here is you did not read the sticky thread to realize, we have nothing to do with the Mac version, and thus my total confussion, when you did not mention that you were a MAC user. ;)
