I just finished a Google search for "Windows 7 program won't start" and found this, "
Windows 7 won't launch programs".
There's two methods that could trouble shoot this problem. The first has you running in Safe Mode and checking for conflicts. The second has you following these steps for: "
Can't open .exe files in Windows 7" by opening the registry and changing a few things.
Guess it wouldn't hurt to follow some of these methods to see what happens.
==================
On an additional note bugs, we hadn't gotten into the possibility that your computer may be infected with a virus. No one asked what kind of virus protection you have; whether you've checked your computer for virus's lately? Nor, do we know if you've got an updated virus list for checking.
In this same thought, do you also have the latest updates for Windows 7? I see there's a Service Pack 1 (SP1) for Windows 7.
Could be we're looking up the wrong tree suspecting the game has a problem when the computer might be to blame.
I was continuing to look for solutions and ran across this Windows Support question: "
You cannot start programs when your computer is infected with the SirCam virus". Seems the very same solutions that I found earlier are directly connected to this specific virus.
