Welcome to the forums.
Requirements to run a Simulator are documented here:
I note Windows 8 is not listed, so I am not sure if that is supported. You might like to try bringing it up in some compatibility mode.
The other thing that I have seen but not experienced myself, is issues with permissions. I install all the BB software in a specific directory, not the standard Program Files. Since I believe the Simulators update files in that directory, this can cause problems. So you could try them in a BB specific directory, or running them as Administrator.
If this does not help, please give us specific information about how your Simulators 'crash'.
