help! why can't i play DOOM on vista?
okay so i downloaded doom at my friends house, cause i realized i had not played it for a while. So i played it at his house for a while then i saved it on my flash drive, when i got home i started it up and it says "This system does not support fullscreen mode. Choose 'Close' to terminate the application",the title of said window is "16 bit MS-DOS subsystem". My friends computer runs XP, while mine runs Vista Home Premium, I figure this is part of the problem. will someone please tell me how i can fix this? Please?!
