Step-by-step procedure to install Turbo C++ on 64 bit Windows 7 and Windows 8 using Dosbox.

1. Install the software DOSBox ver 0.73
2. Create a folder,for example „Turbo“ (c:Turbo)
3. Download and extract TC into the Turbo folder (c:Turbo):
4. Run the DOSBox 0.73 from the icon located on the desktop:

5. Type the following commands at the command prompt [Z]: mount d c:Turbo
[The folder TC is present inside the folder Turbo]
Now you should get a message which says: Drive D is mounted as a local directory c:Turbo

6. Type d: to shift to d:

7. Next follow the commands below:
cd tc
cd bin
tc or tc.exe [This starts you the Turbo C++ 3.0]

8. In the Turbo C++ goto Options>Directories> Change the source of TC to the source directory [D] ( i.e. virtual D: refers to original c:Turbo .
So make the path change to something like D:TCinclude and D:TClib respectively )

How to start TurboC++ in the DOSBox automatically:

You can save yourself some time by having DOSBox automatically mount your folders and start TurboC++:
For DOSBox versions older then 0.73 browse into program installation folder and open the dosbox.conf file in any text editor.

For version 0.73 go to Start Menu and click on “Configuration” and then “Edit Configuration“. Then scroll down to the very end, and add the lines
which you want to automatically execute when DOSBox starts.

Automatically mount and start Turbo C++3.0 in DOSBox ver 0.73:

Scroll down to the very end, and add the lines:

Please note:
Full screen: Alt and Enter
When you exit from the DosBox [precisely when u 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 . Eg : Ctrl+F9 will exit DOSBOX rather running the code.
