Otrex have you checked your "Data Execution Prevention" (DEP) settings, if its switched on which i think it is as default in 64 bit Vista Ultimate this can stop the game running by blocking programs running that use certain parts of computer memory.It seems to affect only certain programmes that try to use certain parts of memory, when i switch DEP on certain games i have still run ok but others dont, TOW was one that would'nt run. Check the TOW troubleshooting guide about DEP or do an internet search for DEP Vista.
Think settings are in your windows system\maintenence section? Its a bit beyond me but know it can stop programs running. Had tried switching DEP on in my Xp pro 32 bit and it stopped TOW running until i added certain TOW executes into the DEP exceptions tab. Like i said above i think DEP is switched on as Default in 64 bit Vista for all programms (not just the vital windows progs) so that could be your problem.
The DEP section in TOW troubleshooting guide tells you which Executes etc to add to the DEP exceptions tab if you can work out how to do it. Or better still turn DEP off if its possible in 64 bit Vista.
