After clicking the install button on the autorun program, it just sits there with setup.exe consuming 1,816KB of RAM. It doesn't progress to the actual installer and doesn't show any errors or crash dialogs etc.

How do you fix this or better yet, is there an alternative installer for this game like there are for Worms Armageddon?

I figured it out, configure Setup.exe to run under Windows XP Service Pack 2 compatibility mode then run it, at the first prompt untick the Clapper along the bottom then press the button to begin installation.
