How to install and start Turbo C++ on Windows 10 x32 / x64

  1. Download and install :
  2. Download the Turbo C++ files:
  3. Create a folder, for example „Turbo“ c:\Turbo\
  4. Extract Turbo C++ into the Turbo folder c:\Turbo\
  5. Run the DOSBox from the icon located on the desktop and type the following commands at the command prompt [Z]: mount d c:\Turbo\

Now you should get a message which says: Drive D is mounted as a local directory c:\Turbo\

  1. Type d: to shift to Drive D


  1. To run the install type: install.exe   and press 2x Enter


  1. Enter the Source drive: D and press Enter to continue


  1. Enter the Source path: \ and press Enter to continue


  1. In directories specify where Turbo C files are copied, e.g. D:\TC . When done go to start installation and press Enter


  1. Successful installation – press any key to continue to view readme file


  1. Successful installation – to exit press [ESC] and close DOSBox. Installation of Turbo C++ is done



Start TurboC++ in the DOSBox automatically:

  1. For DOSBox versions older than 0.73 browse into program installation folder and open the “dosbox.conf” file in any text editor. For version 0.74 go to Start (press key [WIN]) and find “DOSBox 0.74 options“ in all app menu


  1. Scroll down to the very end, add the lines below, save, close and run DOSBox now:

mount d c:\turbo\


cd tc

cd bin



  1. Automatically mount and start Turbo C++3.0 in DOSBox



Please note:

Full screen: press [Alt] + [Enter]

When you exit from the DOSBox [precisely when you unmount the virtual drive where Turbo C++ 3.0 has been mounted] all the files you have saved or made changes in Turbo C++ 3.0 will be copied into the source directory (the directory which contains TC folder)

Don’t use shortcut keys to perform operations in TC because they might be a shortcut key for DOSBox also. E.g. [Ctrl]+[F9] will exit DOSBOX rather running the code.


How to use [Ctrl]+[F9] (“Run”) without closing down DOSBox

  1. press [ctrl]+[F1] while running Turbo C++ to view/change the mapper commands.
  2. click on “ShutDown”,
  3. then (click) on “del”,
  4. then (click) “add”
  5. and then press q on your keyboard. Then click “mod1″ in the lower left corner to close DOSBox with [ctrl]+[q]
  6. click on “save”

Now you can use [ctrl]+[F9] in Turbo C++ as usual and [crtl]+[q] to close DOSBox.

You can do the same with [ctrl]+[F1] (for topic search) by clicking on “mapper” and changing the command as described above.

To reset the mapping, just run the “Reset KeyMapper”-file in the DOSBox folder.
