Halo 2 vista wont start.

I instale Halo 2 with the dedicated server and all that and it went succesfully when i tried to play it said the game cant load because dedicated server might be running. when it wasnt. and it said to reinstall to fix the problem. i did reinstall it without the dedicated server and same message pops up. how can i fix this?

did you uninstall the dedicated server when you re-installed? You could also stop the service running via services.msc(type in start menu).

i dont know if i did all i did was uninstall halo 2 using add/remove programs theres no dedicted server on add/remove programs or services.msc

can you navigate to (x being default disk drive) x:\Program Files (x86)\Microsoft Games\Halo 2 Dedicated Server and tell me what's in that directory? if anything is in there, then you need to delete it and restart, if it says the program is in use, then start in safe mode and delete it, restart and try playing halo 2 again

i tried that thers nothing all there is under microsoft games is halo 2 and its files no dedicated server

very strange indeed, if anything it should be working now i can only suggest a system restore if its enabled to when you installed halo 2, failing that, theres nothing more i can suggest

nah im not gonna bother. i installed all new updates and still no sucess but its like the game thinks it there when its obviously not.

Have you tried running as admin or in compatibility mode?

yes but no sucess i have installed it before and played but like i reinstalled vista and now it wont work
