The program comes from Leecher1337, who created a NTVDM for x64 bit.

I've tested on many Windows via VirtualBox, it worked half a time. (Worked on Windows 10 64 bits). Running DOS Application worked, I've tested on Foxpro 2.6 for DOS. I know that NTVDM is the composant used for x32 to run 16-bit apps.

Here are my questions :

  • Is that program trustable ? (I don't have knowledge to answer this)

  • In terms of security, is there any problem? (If I want to setup this in Enterprise)

  • Is it efficient for a production environment?

NTVDMx64 is referred by several sources as trustworthy, but this is finally your decision to make. You should know that it's very slow and uses non-standard methods of loading programs.

You may also look at the following alternatives:

  • vDos (donationware) is better for most purposes

  • DOSBox is also a worthy alternative.

NTVDMx64 is fine. It does its work (loading 16bit programs) and nothing else. We can all agree it is slow as hell, but thats normal. I use it in a production environment and it works fine, much better than DosBox, at least for my particular needs.

The problem here, as I think most users didn't notice or care, is that, with this, also comes the ability to once again run the old 16BIT viruses from the DOS era. So, if you plan to do this wonderful trick, be aware it may come with the chance to infect your machine/network with some old nasties.
