Installing fonts to Illustrator CS6
I have fonts on a CD and I want ot load them into Illustrator CS6 so that they will be permanently available when I am working in Illustrator.
Generally speaking, you should install fonts on your OS, not a specific program. You can make your fonts available to Illustrator without installing them on your OS though.
From Illustrator Help / Fonts:
In addition to the fonts installed on your system, you can also create the following folders and use fonts installed in them:
Windows Program Files/Common Files/Adobe/Fonts
Mac OS Library/Application Support/Adobe/Fonts
