Plutonium

Fendexx This just means you didn't configure something properly so your Windows doesn't know which software he should open torrent files with. Now if you followed exactly what I showed you your PC will always open torrent files with qBittorrent.

Fendexx Alright, I had a video explaining how to fix that on my PC so here you go

mistahanto If you didn't read the Custom games with friends guide then read it and follow the instructions. If you did and it's still not working this either mean you did something wrong or something is still blocking the connection on the host PC like his firewall or his antivirus firewall

Fendexx Your message isn't clear at all. If you have trouble getting the torrent file then you should open the link in another browser like Microsoft Edge as it's an issue with your browser.

hugoraboloko Delete plutonium.exe and plutonium.new.exe and download a new copy of the launcher here: https://cdn.plutonium.pw/updater/plutonium.exe
Then place the new exe anywhere you want: on your desktop or in your game files folder for example and run it.
The update process will start and you won't have anything more to do next times, only run plutonium.exe and it'll automatically update

skyluz To add to what mulekick said Plutonium doesn't support Windows 7 and probably never will as it's just a waste of time. You should upgrade to Windows 8.1 or even better Windows 10.

seejayyyyy For multiplayer probably yes. You should see something about resolution, you could search (ctrl+f) keywords

Atzouk Are you sure that only the console opens? If you hover your mouse on the BO2 icon in your taskbar there's only the bootstrapper showing, no Black Ops II?

PhilosophyBits No one here told you to use this link.. Read the official Install guide instead of using potentially outdated/malware filled files

mayood232 You either have a software with an overlay running so try to quit any program that could have an overlay before starting the game or one of your plugged in devices crash the game so try to unplug everything but mouse, keyboard and main monitor before you start the game (VR headset, other monitors, controllers etc.)
Also what is your antivirus? (even if it is disabled)

MohadailyOnYT Bans only happen if you mess with the game (aka cheating) and a ban this long means he already got banned and this is another ban

BoscaDunFear then you either have a software with an overlay running or one of your plugged in devices crash the game so try to unplug everything but mouse, keyboard and main monitor before you start the game (VR headset, other monitors, controllers etc.)

pepsi con limon on your second screenshot are you sure that "Internal host" is your PC? Also as the guide says make sure to be in-game to be joined.
If you did all that then maybe that's your issue:
even if you did everything correctly some softwares can still block the connections like your firewall or your antivirus firewall.

Beposparuga If you're using pluto_t6_full_game then try to repair your game. If you're using your Steam files then did you download the DLC? If not then obviously the game cannot load DLC without DLC files. You could either install them on Steam if you own them or follow the T6 DLC guide.

seejayyyyy Try switching between windowed borderless and fullscreen mode, I'm pretty sure one of those two will have the option. If this still doesn't work you could change your resolution in the config files

Veofiy afaik there's no voice chat planned for BO2. You could use Discord instead. If you're playing on a server that has their own Discord server you could check if they don't have voice channels there and ask people to join or if there's none you could ask people to join a voice channel on Plutonium's Discord server

Envoi une capture d'écran de l'erreur complète. Ce code d'erreur ne veut rien dire voire même n'existe pas

Jonesii You could try to repair your game

LauEchev adunkee preggerz_mgee Try to download and then run Redist-Installer.bat, let it finish to install the required redists then restart your PC and try again.

Heppell are you using your Steam files? If you don't own the DLCs and try to play them without downloading them in the first place it will obviously not work.
For Steam you can follow the T6 DLC guide on the forum, for the torrent you can just follow the instructions on the message above mine
