When I first install Nox, I can launch it fine until I exit out of it and try it run it again. Nothing happens. I don't think Avast is blocking it. I'm using Vista.

This happen to any one else?

Try uninstalling vista and installing a better OS

superjack46 you could try to be more helpful. im encountering the same issue even now...my laptop is on vista and i dont feel like spending $100+ for windows 8.

Windows 7 and same issue, nox is borked, bug fix release would be nice, but without a debug build we will never know what's the issue any way's... :( this was a rather bad bought luckily it wasn't awfully expensive...

I spent $15 for Windows 8.

You must not have been paying attention to the Microsoft special they had for at least a month.

To everyone else: The game runs fine but Vista...ugh...Try upgrading to at least W7.

I am running on Windows 7 x64.
