NTVDM

I am trying to install an application and when i run the setup I see the busy cursor on my mouse but when I go in the processes I see the NTVDM (Virtual Dos Machine) take 100% of my CPU and I have to kill the process manually since nothing is happening.

I am using NT and i am looking for a way to get it to work since it’s a 16 Bits Dos apps.What can I change in Nt to get it to work?

Thank you.
