Plutonium

david38484884 "The minimum requirements for the Pluto launcher is .NET 4.7.2," well 3.5 is below 4.7 and 5 is above 4.7...

Jomusus you could just read the pinned topic in this section

Brandon8A this is not the WaW section + I'm pretty sure you could easily find an answer to this if you searched a bit but anyways.

Just like any other Call of Duty game you have to be at least level 4 to create a class. If you want to unlock everything you can type /unlockall in the console.

You can change the fov by using this command:
/cg_fov value

S0beK try to delete the Plutonium folder in %localppdata% while the launcher is closed then open it again. Also what is your antivirus?

You could try adding both the Plutonium folder and your game folder as exclusions by following this guide.

vilemytyt send a screenshot of the error. Note that if you are on Windows 7 you'll have to upgrade to Windows 8.1 or Windows 10 as mentioned in the Common Launcher Issues & Solutions topic

snaggingbat72 I don't know, I doubt that something changed on Plutonium side, that's probably on your side idk. I just said you could give it a try but I don't know more

snaggingbat72 you could port forward instead

SirMenter you should port forward. uPnP is basically automatic port forward but it doesn't work for everyone

Abrikot
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

Abrikot if you're using your Steam files then go on your Steam library > Black Ops II > right click > Properties > Language.
If you're using the torrent then either buy the game or find the language files yourself.

Wikipedyalite maybe you're joining an hardcore mode server or a server that has disabled hud? I think there's an option to disable it on your game too make sure you didn't disable the hud. Last thing you can do is try to repair your game.

HugroShlag I'm pretty sure you can't

@Hotdogs121 "For example". He asked what a root folder is and that's what it is. The path is something else. Basically the root folder of the players folders is the Black Ops II folder.

possaaa that's not what the Server Hosting is for but you could try to take a look at the FAQ (ctrl+f search "server").
This could be an issue with your router or firewall or your antivirus firewall

G1itchz Click on the arrow on the Play button to switch to LAN mode then host a game normally, follow the Custom game with friends guide

MarioloPantoja that's what I said yes?

Gugus pleindsel Plutonium doesn't run servers, other players do. Report to the server admins on their Discord server or website. You'll find those information on their server
