Just curious hyah, I've just installed RR on me new system, everything runs fine; but I sem to remember that on my old machine I managed to change the key bindings, and now I can't remember how.

I've tried running 'SETUP', but it just tells me that the exe isn't compatible with my version of windows (being windows 7 64-bit); I've tried running in compatibility mode but no joy.

Can anyone giz a hand?

You have to run setup.exe from within DOSBox, it won't work within Windows 7 64-bit. If you've used the GOG installer then there should be a shortcut to launch the setup.exe within DOSBox.

Also, it helps to run as administrator (or have the game installed outside of Program Files) otherwise your changes may not take effect.
