Making a Dos VM for an old Software

I have both experience with DOS itself (primarily with the 6. version back in 1990s) and some recent experience with DOS emulation software possibilities. I will check your link a little bit later. You might contact with me to discuss the details. *** UPDATE *** (below) Have successfully installed the file within a VM. The program running without noticed problem. I can send the whole VM in reply. Size is ~40 MB. If you think so, I can give Teamviewer access to my computer for you to check the functionality of the program in advance.
