msg 'NOT A VALID WIN32 APPLICATION'?

[aclinml]

Should be a simple question. Newbie working with his first Windows Mobile device (ATT 8525)

My first attempt to add a program to my device. I downloaded ICONTACT 0.4 from FREEWAREPOCKETPC.NET. It was a ZIP file that contained one item, ICONTACT.EXE. I was expecting a .CAB file.

When I double click on the EXE file on my PC, I get the following message

(NULL) IS NOT A VALID WIN32 APPLICATION.

I tried to go ahead and copy the EXE file to my phone, and execute it there, but all it did there was give me a 'black' screen.

What is my problem????
Thanks,
Mike
