In order to use a braille display or a speech synthesiser, you have to download the drivers you need according to your equipment.
First, check that the 'c:\Installation BS4' directory exists on your computer. If it is not the case, you have to go to the preliminary step. It's better to install BrailleSurf before drivers.
To install these drivers, just run the downloaded file. You will be asked for the directory in which BrailleSurf 4 is installed. Then the program will invite you to activate the installed driver.
