Installer script

[jheriko]

I've just finished my new installer script, I thought that maybe some of you people here might prefer this method of installing to Winamp 2 or 3 (but still not both unfortunately) to the one using those messy message boxes. This one uses the 'Install Options' menu to choose between Winamp 2 and 3 like my old script but it also autodetects the install directory.

I've used my last minipack for the example script here. Please tell me if you find any bugs!
