A friend of mine has been having a problem installing the MOHAA Breakthrough expansion pack.

It seems to me that the files in the eReg subfolder of the install cd is defective.

The message returned sounded like

J:\eReg\Medal of Honor Allied Assault Breakthrough_code.exe is not a valid Win32 application.

I have verified that he already has the MOHAA installed previously and this is the first expansion pack he is installing for the game.

Can somebody point me to a site where I can read more about this? I was kind of hoping that I might be able to download a copy of the damaged file/s from the internet.

It will also be very helpful if someone could advise whether it would be possible to run this expansion on his system consisting of the ff:
P3-450 MHz, Asus V7100 Pro, 640MB SDRAM, 30 GB HD.
