Warzone Wont Launch/Update Bug

having that same issue right now

Idk about you guys but i just tried this suggestion and it worked for me.

We get a dev error that pops up before the splash screen finishes loading *when launching from .exe as admin.

think i found a fix. if your running the -d3d11 delete it. Give it a shot it’s the only thing I did outside of running as administrative (which didnt work) did this fired up 1st try. let me know if it works my fellow gamers

I just fixed it by following a guy from spain video on youtube WARZONE NO INICIA - ERROR BLZBNTBNA00000012 ASI SE SOLUCIONA - YouTube

Basically:
open the file where MW is installed, then CUT MW file and paste it on a different file but in the same HardDrive.
Then open task manager and end tasks for Battlenet , look closely there might be several (scrolll down)
then open Battle Net, Settings, Downloads, Scan for Games, Locate, then select onpen the file where you pasted MW, then select MW . Done.
Then you should be able to click Play.
I had to do it twice and it worked.

Only thing that works is to run battle.net as administrator. Must be a kernel anti-cheat permission bug. Just locate it, go in compatibility mode and check Run as administrator. Hit apply, restart battle.net and you should be good to go.

wow you’re a life saver anybody having this similar problem this is the fix .

This one fixed it for me (same one I posted above):

After doing this the scan failed at 100%. But, after relaunching battle.net client the quick update went thru and it said ‘Play’. The game still did not launch, but the files were all back. Launched successfully from the .exe, quick restart for update, again had to launch from .exe and I’m in!

Tried this already, twice. Did not work.

Tried that fix as well, it also does not work. Deleted the files, did the scan and repair, it cannot update because the updater is broken.

I felt compelled to come back here to help you guys. I tried all of these solutions here to no avail. I just found a solution that got my client to load. From the front screen like before you click into the “Warzone” portion of the application you can access your settings. Reset all of the graphic property’s back to default. After I did this my client was able to load again.

Cheers!

I can confirm that this also worked for me! After completing the scan it failed but I closed the launcher and opened the .exe from the game folder and there was an update of about 13 megs and I was launched into the game. It did ask if I wanted to start in safe mode which I did and setup the graphics once again. But I can say that this does work. Don’t worry about the first part, the second part worked like a charm!

Hell Yea… Thank you!! Worked for me as well

can confrim. this works for me as well! cheers! thanks!

No fix at all. The update is broken. Anything that needs an update will NEVER be a fix.

I did exactly as it says, it took about 1 hour, but now the game opens, thanks !!

I have the same issue, I’m thinking its a bug on Activision’s end.

works, but crazy stuff happens in between matches for some reason. gotta force stop after each match

It worked , Thank you a lot
