Call of Juarez Gunslinger – Refusing to Launch (Fix)

Hey guy’s, this is just a quick fix i’ve found that could help some of you out there that cant launch the game at all.

If you cant boot the game, its mostly because your cpu has more than 10 cores from what i’ve read online. At first i believed it to be bogus but for whatever reasons it worked for me so i figured i’d put it as a guide for you fellas out there.

The Fix

The fix which worked for my Ryzen 9 5950x.

Go to task manager and look for steam32bit and right click it then select go to details.

Right click steam.exe, set affinity.

Then untick every cores except 0 up to 10. (To undo these changes just click the top option to enable all cores again in the affinity menu).

I personally dont understand why this fix works.

I love games and I live games. Video games are my passion, my hobby and my job. My experience with games started back in 1994 with the Metal Mutant game on ZX Spectrum computer. And since then, I’ve been playing on anything from consoles, to mobile devices. My first official job in the game industry started back in 2005, and I'm still doing what I love to do.


    • It worked for me when I set the affinity on the game .exe, not the steam .exe.
      I also used Process Lasso to make the setting permanent.

  1. Thanks for your work!
    May I know that if I reduced the CPU core for steam.exe, any performance reduction for other games? Thank you so much!
