HannesC Ive tried that and restarted the pc, but again, same error. Maybe cuz my windows is X64 and the launcher is 32bit?

Dss0 thank youuuuuu man

Nah none of those worked. But looking in my %localappdata% files plutonium isn't even there, im assuming thats probably the issue.
Thank you for the help though.

geroomv Try installing this https://drive.google.com/file/d/11BAlZId09Bo0C2yo2CtaOLl0QmRZAJcm/view?usp=sharing

feth4you first issue is covered here https://forum.plutonium.pw/topic/6832/common-launcher-issues-solutions
second issue means you selected a folder that doesn't contain bo2 files, did you select F:\Bo2\pluto_t6_full_game in the game settings?

Sk9erDude if it is for cod waw or cod bo2 then you have to select the folder with fully installed from torrent and for cod mw3 , you have to install it from steam

KmKz Rigby move it to your desktop, program files (x86) requires elevated permissions.

Windows 7 is not supported, even if you get the launcher to work the games won't. You have to upgrade to Windows 10 or newer.

The launcher updates itself when you start it. If it's not doing it this means you pinned the launcher while it was running.
To fix this unpin Plutonium from your taskbar, make sure Plutonium is closed and pin plutonium.exe again.

If this still doesn't work maybe getting clean files from the install guide would fix this.

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...

Client files automatically get downloaded when you run plutonium.exe, whenever there's a new update. So yeah that's normal.

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.

RoadRunnxSJ send a screenshot of the error

Upgrade to Windows 10.

eseldazz try deleting %localappdata%/Plutonium/info.json, also try running the launcher as admin.

Dss0 thank you dude

azariy damn if only someone answered @lResxt question 🤔

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
