Running 16-bit app on 64-bit is now possible? NTVDMx64

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.
