Elaborate or atleast provide a screenshot of the error?

@snipergang you need to launch it through the plutonium launcher, launching the server exe directly won't work. Have you tried all of the troubleshooting steps outlined in this topic? https://forum.plutonium.pw/topic/6832/common-launcher-issues-solutions

@fortniteamongus works here, try restarting the launcher and/or deleting %localappdata%/Plutonium/info.json if it doesn't work for you.

@blackops23 it should be working already

Server issue, we all have the same error

We only support 10 or newer.

@ayoub64 covered here https://forum.plutonium.pw/topic/6832/common-launcher-issues-solutions

Too old build, you need windows 10 1607+ to play on Plutonium.

WIndows 8 isn't supported. Upgrade to Windows 10.
