Well, I've got it installed and running but it crashes occasionally, any tips on settings and how to fix it?

Make sure compability for xp, administrator mode are on

Yep done that, thats why its running, but is there a tweak for DirectX 10 or 4GB of RAM, and do you tweak the .inf file....you know stuff like that not the obvious.

Try google.com

Yep done Google, just thought what with this being a dedicated website to the best games in history that someone would have some good tweaks....

The game worked fine for me on 32 bit must be your 64 bit.

I've just used Lennards cleaner on it and its worked a treat...UBI rather than banning him for sorting out your very buggy Double Agent you should employ him and pay him for sorting out your problems.
