Install error!

Greetings! I have just downloaded Vassal this evening, was disappointed to discover that my system didn’t want to run the installer, with a peculiar error message. “C:\Users(Me)\Downloads\VASSAL-3.1.15-windows.exe in not a valid Win32 application.”

I am running:
OS: Windows 7 64bit
CPU: AMD Phenom 8750 Triple Core Processor 2.40 GHz
Memory: 4GB
Video: EVGA nVidia GeForce 460 GTx
VASSAL: 3.1.15
Java: 6.0.23

Nevermind! Got it running, for some reason I lost data in the download three times in a row, so it couldn’t start. But once I tried again this evening the file came complete, and installed perfectly.
