already share ki ja chuki hai.

Its your choice! 

Simply issue is, 'Unsupported 16 bit application'

but seems there is no solution except to change window..

No many solutions are available.

  1. Use dosbox it is only for 64bit windows.
  2. VMware or virtual box or microsoft virtual machine in windows.
  3. Set bcc.exe file with windows 98/ME compatibility mode then run on dos.
  4. Run dos application in windows with vDOS download link

Hope it helpful for u and others........

Thanks you.

I'm using same. DOSBOX.

even have successfully done my previous one assign.

current issue was just creating .com file which was especially required in this Assign and could not be create due to compatible issue.

anyways, will try vDOS for the next time. if acceptable by instructor.
