So, I was asked many times why people are sometimes not able to use certain Legacy Arabic Fonts inside InDesign CS6 ME version, mainly AXT fonts.
First of all, make sure that you are using the "Middle East Version of InDesign CS6"
Problem Definition
So, what happens when you type or select Arabic text, and try to use an AXT legacy Arabic font like "AXt-Manal"?
First you will receive a message that informs you that "Missing Glyph Protection has occurred...", and then nothing happens, as you cannot use the AXT font.
In order to fix this problem, you will need to go to the InDesign Advanced Type Preferences, and turn off missing Glyph Protection options.
Select: InDesign -> Preferences -> Advanced Type
Turn off: "Protect While Typing, and Protect While Applying Fonts"
After you have done this, you can now use AXT Legacy fonts and apply them to Selected Fonts.
Good Luck
