How to Run or Install MASM Software on Windows (32 or 64-bit) using DOSBox 

Most of the Students doing their courses in Computer science & Information Technology using windows 7 or Windows 8 find it difficult to use few programming language because of few compatibility reasons. And one among them is MASM 8086 Software also, which doesn't run on windows 7 systems easily whereas in you find it easy to run this software on windows XP, windows server 2003 and also windows 2000!

              So in order to run this software the solution to change the OS doesn’t sound good or easy right! :D So to get rid of these compatibility issues we have a open source software named the DOSBox! This is basically a X86 DOS-emulator that uses the SDL-library which makes DOSBox very easy to port to different platforms. DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux, MacOS X...! Presently 0.74 is the latest version of DOSBox.

       Well, now let me come to the point i.e., the tutorial on how to run MASM 8086 Software on your System. I will explain it to you step by step :-

► Initially you will have to Download two files to proceed with the further steps. So download the below given two files :-

File 1 - DOSBox 0.74 Installer – DownloadLink !

File 2 - 8086 Assembler – Download Link !

► Now as you are done with the downloading part next you gotta open the second file which is a compressed file so you have to extract the files in it to the C Drive of your system.

For that just select the 8086 folder > then click on extract to option > then select C Drive > finally Click on Ok!

Follow the image shown below step 1-4 !

► Then next you have to open the first file i.e., the DOSBox file and Install it which is simple just keep clicking next > next > install and finally close.

► A shortcut of the DOSBox will be created on the desktop so goto your desktop and open the DOSBox icon.

► Then you will find that a black screen pops up. Now enter the command as shown below :-

           MOUNT C C:\8086 (and press Enter)

A message will pop up saying Drive C: is mounted as Local Directory C:\8086\

► Next type the below command :-

           C: (and press Enter)

So now it will enter into the C Drive !

► That’s it you are done! Finally you need to Enter the following command to enter into the MASM Software.

           EDIT filename.ASM (and press Enter)

Now you will enter into the MASM Software Screen. J

Note : If you are a XP users you need not download the DOSBox you can directly download the 8086 Assembler and run it through the Command prompt as usual.
