Installing KQ7: which files to boot?
 

I'm trying to install King's Quest VII which I downloaded from myabandonware.com.

I'm using Dos Box Game Launcher and I'm unsure of which executable files to select for the "Main" and "Setup" fields. There are a LOT to choose from (inst, setup, sierra, sierraw, autoplay, bootdisk, etc).

I have used many combinations of these applications without success. Can anyone help me?
