Not a valid win 32

[Dabloon]

I followed the most recent guide exactly as it said to. I did this twice on 2 different computers. One with windows 7 pro and one with windows xp pro.
The windows 7 compile runs flawlessly. The xp pro sever however comes with an error saying its not a valid win32 application. I have already verified that none of the files are corrupt by moving it to another of the many win7 pcs in my home and it booted flawlessly. This leads me to believe that the xp pro machine is missing something all the win7 machines have but i can not figure out what it is. Any help would be appreciated.
