Can't say for sure. I haven't touched Windows for quite some time, Plus-X, as BloodScourge suggested, might be your best bet. If that doesn't work, I made a script that sets executable permissions for the user and then runs the game. You could put it in a text file ("start_somnabuster.sh" or something like that) Hopefully that helps some.

#!/bin/bash
chmod u+x chrome_crashpad_handler nacl_helper nacl_helper_bootstrap somnaBuster
./somnaBuster

I'll do some research on the subject and get back to you if I find anything helpful.
