my only question is im running an SSD drive with only 250 GB so i put all my games an luncher in D drive…an its already got an battlenet folder in there…what do i do with it? delete it an make a new one like you said?
It doesn’t work and I have tried many solutions that was provided by the community and sadly none of those works either. It’s an ACTIVISION ISSUE and they need to fix it A.S.A.P for the community
I believe you Joynueer, I believe you man 
@Joynueer - Thank you for confirming the issue! Been helping a buddy with this problem and it’s been super frustrating picking up hints/tips here and there and trying EVERYTHING under the sun to fix the problem (moving folders/scan&repair/deleting files/running as admin/etc etc).
Really looking forward to resolving this, please let us know as soon as the patch is live!
Thanks very much!

I think thats all BS patch is out or coming out…thats just to calm everyong down…its been hrs now an still no patch…its all garbage like acttvision an battlenet…there all a f…ing joke…they will never ever get a dime out of me again…im totally piss off at these clowns
I assumed the patch was out when I redownloaded battlenet and was able to launch warzone. but after playing 2 matches it disconnected me from the servers and starting giving me the same BLZBNTBNA00000012 error. which I’ve had for about 34 hours now.
any update on the patch? i’ve been waiting the whole day and no update has been sent.
Alright @Joynueer, it’s been 9 or 10 hours since you said “soon” for the patch. Totally understand it’s not under your control, but an update would be awesome!

Create a new folder.
Move CDWZ there.
And the game starts
if you follow the simple video instructions this tip works.
Never seen a game like it for issues… complete joke
Hey all,
It looks like the patch for error BLZBNTBNA00000012 has gone live. If you are still experiencing this error, please try the following:
- Run the Battle.net app as admin
- Move the game install folder to a new location
- Disable any command line arguments in the Battle.net settings menu
If there are still any “BLZBNTBNA00000012” messages popping up after all of the above, please reply to this thread and let us know.
If you are experiencing any error that is NOT BLZBNTBNA00000012 please create a new thread. Unrelated issues will not be addressed on this thread which is specific to that error.
Thank you.

When trying to launch the Warzone game, I would receive this error “BLZBNTBNA00000012” “An error has occurred while launching game. Please check for updates or scan and repair to fix this issue.” I have tried many solutions from the community and Activision support, and none would. I would like your help in fixing it, thank you.
