You need to install windows 3.1 through dosbox. There should be a preinstalled zip floating around. Then you can run exile 3 from there, after setting the VGA to 256 colors and installing the sound blaster 1.5 driver. Funny thing is, on my laptop, exile 3 works perfectly without any sound breakup. But on my desktop, which is much faster, the sound breaks up and lags. Both with clean installations of dosbox.
