CoD Modern Warfare Warzone fatal error at startup
Need help fixing Warzone starting up. I am getting an error starting the game up.
Here is the error message.

Fatal Error 0x00000001410b9550 7497748
0xc000001d ModernWarfare.exe

The game does not load into the main menu or logo and I don't know why. Can anyone help?.

I have not been able to play this game, and it has not loaded to main menu not even 1 time.
Maybe there is a codec or Microsoft C++ program I need to have installed?. Please help as soon as possible so I can play this cool game, it looks awesome.

Here are my system configurations.
Core 2 Quad Q9550 @ 2.8
Nvidia GTX 960 2gb
DDR3 8gb
Windows 10 x64

It's a pretty stupid and trivial instruction though, so you may want to try to ping the devs if they can remove it.

The post should be alright here on Steam.

The Help and Tips forums is for Steam only, this isn't about steam or a steam game.

I didn't know about POPCNT, now I know it is my cpu, thank you. I hope they update the game soon so people with Core 2 Quad cpus are able to play the game.

Bye and have a good day.

I'm not sure if they know in the first place though, especially considering this annoyance is there at least since the beta 6 months ago.
Make a thread on their forums and ask if some dev can check it.

hello everyone, I have this problem and the cpu is not supported because too old suddenly go your way those who have an Intel core 2 quad Socket 775/771 or AMD Socket AM2 +.
