If you're using DOS 6.22 then there will be quite a bit of things that just don't apply to it. The vast majority of operations within KiXtart were designed for Windows 9x and above. DOS and Windows 3.1x just don't support many of the newer feature sets within KiXtart 3.x and 4.x

The 2.x versions of KiXtart should allow you to do most things that are appropriate though for that OS.
