I know its an old game, bu I found it in an old stack and researched how to install it on Linux. I follow all the advice, but I have one problem, as soon as I type anything in the dialog (example, where to install the game to), the install button greys out... a screenshot link is provided below (yes, I realize this is the GNOME support area, but games are games, and KDE gaming area isn't as alive as this one).
Any help is much appreciated!
