Nope...Still can't play...
2 days and I still haven’t been able to launch the game. This is getting out of hand.
No word from the devs or anything. @ATVIAssist doesn’t want to help PC players who payed good money for this game. No one seems to have tested this game other than Windows Vista to make sure that the game works.
Come on Activision/Infinity Ward. Sort your shit out.
EDIT: It took a WHILE but I got it working and I decided to post the fix on PCGamingWiki. Link to fix.
