nvm i got my MW2: Mercenaries Titanium working! for anybody who also wants to get MW2 titanium mercs running on vista 64-bit, this is what u have to do:

1st: Pop ur Mercs CD in and click Explore (or go to Computer, then right click ur CD drive which should have the Mercs icon, and click explore). Then it should show you the files/folders that are on the disk. Right-click Setup, then go to properties. Find the Compataiblity tab in Properties and check the box that says run in compatailiby mode, then in drop down menu choose Win95. This will allow mercs to actually install instead of crash when u click "install".

2nd: Find the MW2 Mercenaries XP Patch, i got it from here . dl & install the patch.

3rd: Go to Computer. Click on whichever hard drive you have mercs installed in, and find the game folder (its prolly in Program Files(x86)). Then find Mercswin and set compataiblity mode for win95. this optional becuase i just realized i did not set compatibility with mine so i guess its not needed.

gl and i still havent tried this with regular MW2.

wow this is an old thread...but anyways i was wondering if anybody knows how to get MW2 Mercenaries Titanium, and i guess while im at it jus regular MW2, on Vista Ultimate 64-bit. I've been playing some MW4 but that wasn't really as good, and MW3 which is awesome, but i still want to play MW2. I just tried Mercenaries for i think the 1st time on vista, and it looked like it was going to work until i clicked install then the installer crashed :\ I have Windows 98SE on a 2nd HDD for dual boot, but i have many problems with 98 since i built my comp with pretty much the newest hardware at the time (it was built in like june 07). On the side, if anybody can help with 98 tht would also be much appreciated. I got internet to work but it doesnt recognize my CD/DVD burner/drive, doesnt recognize sound card, doesnt recognize vid card...and a few oher minor things. Anyways back to MW, i read somewhere tht somebody got MW2 Titanium to work on Vista 64-bit, and he said to install the game 1st, then dl the winXP patch for MW2 (i guess the xp patch works for vista). So i was going to try tht but it wont even install so not much i can do there. Any suggestions?

And btw, for every1 here who wants a new MW game, if u havent heard about it, Crysis is making a full mod called Mechwarrior: Living Legends, its looks sweet. theres a vid on youtube for it and u can look at the official stuff on www.mechlivinglegends.net i dont think its finished yet but they r close the vid says winter 09. MW with the grphics of Crysis is sure to be awesome, as long as they keep the best parts of mechwarrior, like lots of different mechs and lots of custimazition items.And btw there was an MW5 in the works by i think MS and FASA but it got cancelled. They should get Activision and FASA to do another game...or Hasbro, if they r still around.
