Run plutonium.exe as admin. Also add %localappdata%/Plutonium and pluto_t6_full_game folders to your AV's exclusions https://streamable.com/5giauo

Try changing DNS (https://www.windowscentral.com/how-change-your-pcs-dns-settings-windows-10) or use a VPN. Also make sure you don't have any 3rd party firewalls/AVs blocking Pluto.

Menje well it tells you what's wrong. Your C:\ drive is full..

Try using only latin letters in your password.

HannesC if he let me in but played with 2000 ping and go from 50 to 2k -_-

Dss0 o thank's man ❤

XaaX win8 or 8.1? You need atleast 8.1 with .net 4.7.2 to run pluto.

ovnik92 try deleting %localappdata%/Plutonium/info.json. Also make sure your firewall or antivirus isn't blocking plutonium.

What windows version are you on? Hit WIn+R, type winver and screenshot the window.

Windows 8 isn't supported. Upgrade to win8.1 or win10.

darkestmuffin72 which OS are you using? Plutonium doesn't support Windows 7.

If you're using Windows 8.1 or Windows 10 press Win + R type winver and send a screenshot of the window that opens.
If you're not on Windows 7 you can also try running the Redist Installer to make sure you have all required redists. Place it anywhere, run it and let it finish to install all the redists then restart your PC and try again.

As for plutonium.exe make sure your antivirus isn't blocking it. You can get a fresh copy of the launcher from any install guide on the forum.

Dss0 thanks I fixed it

KrzMcCurdi Plutonium supports playing private/solo/LAN games but doesn't support offline. You need an internet connection to play.

HannesC thank you for replaying

Tatatom46 what is your antivirus?
If you're using a VPN try without it. If you aren't using a VPN you could try again while using a VPN to see if that helps.

OwNuT special characters pretty much means any non english character. So yes as said above the é character was probably what was causing the launcher to not be able to read the path.

@MazikeenX only thing I can tell you is that it's using the exe files in %localappdata%\Plutonium\bin with the exes in %localappdata%\Plutonium\games as an argument. Don't know how it works exactly or if it has other arguments but maybe this will help you.

If you're using a game launcher like GOG Galaxy then you could either launch plutonium.exe instead of the game directly or create a macro that starts the launcher and click on Play or wait for an answer from staff.
