Hi and welcome to forums :)
This is a rather vague description, won't you agree? :)
What's your system specification, how does the problem look like - the game won't install/won't launch? Or maybe something else? You need to provide some information and I'm sure someone will help you, or at least try to.

Sorry, you're right, but my computer skills are vague too:)
I have windows vista... And the game won't launch - I guess. nothing happens when I launch it...

Are you trying to run it from the desktop shortcut? If so if you right click on that shortcut and go to properties, then compatibility tab. Click the tickbox for run this program in compatibility mode and then select windows 98/ windows Me. Also check the tickbox for Run this program as an administrator, Click apply and then ok and then try to run the game.

I have tried your suggestion, but it still won't work. It won't even start up. When i doubleclick it just opens a window and then closes it again.

It works:) Thanks for your help. It works with xp, not vista.

That's weird. I have Windows Vista on my laptop and Redneck Rampage from GOG works just fine on it. Maybe your anti-virus software is mistakenly preventing you from running it?
