Yes. If you have FontAgent 7, you can uninstall FontAgent Pro 6.

To uninstall FontAgent Pro 6, do the following:

  1. Open the /Applications/FontAgent Pro 6/ folder.
  2. Run the Uninstall FontAgent application.

Additionally, because FontAgent 7 uses a different folder to store its fonts and database, you may also remove FontAgent Pro 6's database and fonts folders. These two folders should be removed manually as the uninstaller does not delete them for you (I recommend that you review the contents of these folders to make sure you haven't put anything else in them before moving them to the Trash) :

  1. /Users/[your username]/FontAgent Pro Fonts/
  2. /Users/[your username]/Library/FontAgent Pro/
