I have installed unreal gold 5 times now, each time it crashes after about a minute. when I try to launch it again the shortcuts don't work and Unreal.exe is missing from the system folder, what on earth is going on?
Please help me.

If I were to guess, I'd say that an anti-virus program is moving it to quarantine. That's just a guess though. I can't think of any other reason it would disappear like that.

For that, you'd need to go into your AV program and mark it as safe.

If you're not using an anti-virus program, then I'm baffled.
