lousassal321 Posted May 13, 2022 Share Posted May 13, 2022 If you keep getting that annoying 6071 dev error or black screen when booting COD, try this fix. Go the registry editor. (Type in 'regedit' into the Start Menu and hit enter.) Go to this address: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography Change the value of the 'MachineGuid'-key to this: d1eb246e-6243-4460-a88e-5d4e52b1ef6b Then just boot up the game and it should work. Please let us know if this helps! ❤️ Night Owl Team Link to comment Share on other sites More sharing options...
