I originally had this problem and the way I fixed it was thru launchbox (not bigbox). I went to the folder where all the zip files were kept,picked the game i wanted to install and then used express zip to unzip it.This made its own folder in the same directory as the zip files folder then I imported ms dos files and it comes up add folder i added to folder and then was given the option to copy or move filder to launchbox Ms-Dos folder.I used the option copy.it worked now when i click on launchbox I minimize launchbox and the ms dos games come up automatically. Hope this Helps.
