COD MW error 6034

[Cesar753Mex]

I reinstall windows 10 with it's latest  updates, then i install Geforce experience and update the drivers for my GPU, then i copy the full game from my brother's PC to my NAS then from my nas to my PC, Battlenet detects it but the problem comes when i try to run the game, the "run in save mode?" window pops up then I click yes, the game starts to load up but it stops and gives me "dev error 6034 {ww_code_pre_gfx.ff}". Before i try reopen the game the battlenet "MW has started update "window pops up and the "MW Now playable".  This happens every time after i try opening the game.

That's likely your issue. If you can, fully download it from the app instead of copying files as a short cut to waiting 6 hours to download it (or more), as some files get scattered in random places like C/Documents.

well i think that is not the problem because i copy that same file to my brother's PC and it works,  plus I repaired the game on battlenet and that checks all the files

GUYS I HAVE YOUR SOLUTION:

I had the same problem and tried all fixes with no luck. Somehow my common sense worked and I got a solution myself. Go to the folder where the game is installed, right click on ''Modern Warfare'' and ''RUN AS ADMINISTRATOR''.

It worked for me I hope it works for you. If it works, lets play together ;) My game name is ''deadman''

I have the exact same error as @Cesar753Mex. I initially had Warzone downloaded, which worked fine. I got interested and purchased the full game. As I remember it downloaded around ~120GB and after that 6034 on every launch. I have tried most of the fixes (clearing battle.net cache, scan and repair with a combination of deleting the data files) and none of them worked so far. Sadly the 'Run as Admin' tip from @deadman.. also didn't work.

 

I am frequently checking Activision's known issue page for any fixes.
