Samsung SCH-i760

This is my first time with a PocketPC phone...but I can't seem to figure out how to execute .exe files. I figured that since it was a windows mobile device, they would be compatible. However, every time I attempt to click on it, I get a msg saying that those files are not compatible. Is this normal or is it just my phone? The reason I ask is that my friend's HTC Mogul has WM6 and works. Any suggestions? Thanks!
