Recently i posted here a problem with Clipper and XP problem when
using serial ports. The solution i get maybe useful to you too, here
it is: i installed virtual pc 2004 (free edition not vpc 2007 which i
could not make to work with free dos) and then installed free dos on
virtual machine. When you do all that boot up your virtual machine and
install virtual machine additions (add it in your autoexec.bat, to be
able to read/write to real hd) and that's it. Create desktop icon of
virtual machine for user to open virtual machine, in autoexec.bat
(virtual) add lines which open your program. It works perfectly!!!
It may helps!
