BackFreePDF Configuration - Ghostscript and e-mailNext

Normally Ghostscript is recognized by FreePDF. Replacing the Ghostscript Version, you must do nothing. However, if you have several Ghostscript versions Installed, you can select the correct version here.
The same for the e-mail interface. There are several programs that can open an e-mail. Which is suitable for you, depends on your e-mail program.
