Can't play Counter Strike Condition Zero on Windows Vista

Hi,

Condition Zero doesn't work anymore on my Windows Vista 64-bit OS. I played CS on the same laptop awhile back and it worked fine but now after reinstalling it I can't seem to play it.

When run normally I would get

"Available memory less than 15MB! "

I have found that CS needs to run in Compatibility mode in order for it to work but when run Windows XP(Service Pack 2) Compatibility mode, I would get the Loading screen and it would remain like that for hours. And when I open the task manager it would show that the program is not responding.

I have searched over the internet bu can't seem to find a solution for my problem. Please help me out. Thanks.

alot these older games don't like vista for some reason! I had the same problem you had and switch back to xp and the game ran perfectly!!

its like i have to much ram for the game and it cant handle it!! the first halo would lag in vista but when i played it in xp the game ran smooth!!

and im running at 4 gigs of ram with 3.2 dual processor!!
