You might have noticed that MASM (8086) won’t run on Windows 7 or newer versions easily whereas it runs well on Windows XP. In this tutorial, I will show you how to install MASM on Windows 7 and newer versions.

You will have to download two files:

  • DOS Box Installer – Download the file from here.
  • 8086 Assembler – Download the file from here.

DOS Box is an  open source DOS emulator and is available for Windows, Mac OS, Linux etc.

After downloading the files,

  1. Install DOS Box on your computer.
  2. Extract the second file (8086.rar) to C drive.
  3. Now open DOS Box and type the following commands:
  • MOUNT C C:\8086 – You will get a message saying Drive C: is mounted as Local Directory…
  • C:
  • EDIT FILENAME.ASM – You will get a new screen for writing the program.
