Tasm Windows 7|Windows 8|8.1 Full Screen 32bit-64bit Version Single Installer Updated Fullscreen


Hello Guys,

Tasm,or Turbo Assembler/Turbo Debugger By Borland , is one of the most popular assembler used in the world today. it’s used to study the architecture and working of various Microprocessors such as 8085,8086,8051,Pentium Series etc..

But However it doesn’t work / supports the 64 bits of Windows i.e Windows 7 64 bit / Windows 8 Version, so i have created a separate configured Version of the software for the same purpose.,it will run smoothly,with fullscreen mode and has many features such as

  • Full Screen Mode Operation On Windows 7 as well as Windows 8 | 8.1 & Windows 10  for Tasm [Turbo Asssembler,TD,turbo Debugger]
  • edit option of Microsoft Dos editor integrated [ You can now write your program directly with the dos editor  edit in Windows 7/Windows 8 ]
  • Inbuilt MS-Dos Editor 2.026 within DosBox
  • Auto Mounted the Tasm Files such as tasm,td,and tlink [so that there is no need to mount them everytime , not even one time !! :D you open DosBox]
  • Mouse Pointer Support
  • One Click Installer,No Need of configuring anything,installs in seconds and the Shortcut placed on your Desktop!
  • Useful For Students as well as Teachers and Professionals..
  • You can save the program directly within it,and open it next time From the Software itself for editing/Use.

  17. Kovac April 29, 2014

    I have the .asm, .obj and .exe and while trying the Turbo Debugger I get the “Program has no symbol table” error.

    1. Chaitanya April 29, 2014

      Bro try this in the tasm by us and let us know if it works or not TD .exe

  18. Rithesh April 30, 2014

    If I try to link it is coming like illegal command tlink.

    1. Chaitanya April 30, 2014

      It shouldn’t happen 🙁 is the command tasm / or td working for you..?
      try using tlink .obj and tell us the error code please.
      thank you!

  19. Sushmitha May 27, 2014

    Thanks a million 🙂

    1. Chaitanya June 3, 2014

      Welcome Sushmitha 🙂

  20. Pedz July 27, 2014

    Thanks. But how do I open my programs from my usb without copy-pasting them in the tasm folder?

    1. Chaitanya July 27, 2014

      Welcome Pedz 🙂 Actually for opening the programs, you can use any text editor such as Notepad . and if you meant executing them, then 16 bit program execution in 64 bit Operating System is simply impossible without Dosbox, however you can use Dosbox launcher to launch such programs such that they appear to be launched directly.

      Hello Manoj, what problem are you facing in Debugger?

  25. Tore February 15, 2015

    I can’t download it. Avast tells me the file is a Win32:Malvare-gen
    Even when I notify to Avast that the site and file are secure there’s no way to download it.
    I’m using win 8.1 and the last version of Avast 2015 free.

    1. Chaitanya February 17, 2015

      Hello Tore, we can provide you other download mirror incase if you need it 🙂

    I cannot run the followin code in this installation. It compiles and links fine but when I execute nothing happens. I think this is correct code. I saved the hello.asm file in the tasm folder after installation. Any thoughts?

    .model small
    .stack 100h


    dexter db “Hello World$”


    mov ax, @data
    mov ds, ax

    mov ah, 09h
    mov dx, offset dexter
    int 12h

    mov ah, 4ch
    int 12h

    end start

  49. Mohammed Faizan April 10, 2017

    Thank you so much.it works very well but the only thing is that when we give an address(say org 1000h), data gets stored in 1010h. So some tiny corrections can be made😃. Again thanks!

    it appears the link is not working again. I use this package for all the assembler classes I teach. Please update the link so I can set up my lab for fall.

    1. Chaitanya June 22, 2017

      Hello, could you please try the below link and tell us whether is it working at your end for the download?


      Thank you so much for your reply on the link and using our tool 🙂

      1. Barbara June 23, 2017

        Norton quarantines the application. Once it is restored from quarantine, it installs fine. Just to make you aware of this difficulty. I could not install directly or save and run due to Norton.

        Thank you for the work you do to keep assembler available.
