Can't open using Crashtastic.exe

When I try to open Crashtastic.exe on my computer it shows the blue circle spinning and then opens a troubleshooting window saying "Windows is checking for a solution to the problem." It stops eventually only giving me the option to "Close program" I have tried restarting and redownloading. I am using Windows Vista Home Premium 64Bit. It works on my small Windows 7 Home Premium 32Bit netbook though.
