amerzone wont install, please help
 

Hi,
just bought the amerzone dvd rom, which says on the box its compatible with XP. When I put it into the cd drive, it says D:\ is not a valid Win32 application. When I go to run and type d:\EAutorun.exe and click ok (as it suggests on the cd) it also says its not a valid application. When I go in the dvd drive in my computer and click the autorun icon, it says that that is not a valid Win32 application too. What could be wrong? I've got XP and plenty enough RAM for the game to run.
Can anyone help? thanks a lot...
