Plutonium

Hopirri no one does that what are you even saying? You either have shitty internet that starts lagging at some point, downloads that start at some point in the background or the server you're playing on has issues.

@SayKo_ is there anything you're doing minutes before you crash? Like using alt tab, opening an overlay or something like that?
Also you should upload the crash dump so that staff can take a look at it

@SayKo_ What is your antivirus? (even if it is disabled)
Also you could try to repair your game.

sovagekiller12 This error means you didn't select the folder that contains your BO2 files.
Send a screenshot of your BO2 path in the launcher and another of your BO2 files like this

Bryan5 Just upload the videos to Youtube, Streamable or any legit video sharing website and send the link here (or edit your message)

HTM-RALLY-KIDS You have to make sure the map you got from the internet is the exact same files than the server, if it starts downloading when joining this means they aren't the same files. Also could just be an issue with the server itself

@X-F2 You cheated and tried to evade your ban

HTM-RALLY-KIDS Some servers have broken FastDL causing you to crash on join because the files you got from them are broken. I'd recommend deleting the mod in %localappdata%\Plutonium\storage\t4\mods and installing it yourself by downloading it from a website before joining instead.
Then you could start your game and join that server again and this will skip the FastDL part and use your already installed files instead.

SimpleTexT NutKawaiiDesu Plutonium doesn't give access to the campaign because Plutonium's goal is to add features to the game such as a working anticheat, dedicated servers, modding etc.
Since there is nothing to add to the campaign and since Plutonium's goal isn't piracy we recommend that you buy the game on Steam or on a trusted key site.

As for multiplayer and zombies make sure you always start them using the launcher. You cannot switch between multiplayer and zombies using the in-game buttons.

The_R34l_Juan Deja de ver los vídeos de mierda no oficiales que no están actualizados o los virus y lee la guía oficial en su lugar. Para instalar Plutonium hay que leer las instrucciones del sitio web de 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)
