Though built on DOS technology, Windows will not run many older DOS-based programs, even in compatibility mode. Luckily, with the power of modern personal computers, a DOS emulator can perfectly recreate a DOS system and run any DOS program on a new version of Windows.

Step 1

Download DOSBox. DOSBox runs a DOS shell inside your Windows environment without installing a new operating system. Download the install file from the emulator's website, and save it to your hard drive.

Step 2

Install DOSBox. Double-click on the install file and follow the installation instructions to place the DOSBox program on your hard drive.

Step 3

Run DOSBox. DOSBox works just as a DOS system, and accepts typed input commands. Type a command and press “Enter” to execute the command.

Step 4

Insert the DOS program disc into your computer. If an autoplay window appears, close it.

Step 5

Type “mount d :\ -t cdrom” without the quotes, and replacing with the letter label of your CD drive, and press “Enter” to run the disc.

Step 6

Run the program. Manipulate the program using the keyboard. See the program's manual for specific control instructions.
