Al Bayan font to work in programmes

Hi there - can anyone help me

I am using mac OS X Version 10.6.8

I want to use the type face Al Bayan in, Ideally Quark Xpress, or Adobe photoshop or illustrator .. I have it in the computer listing in fontbook and all seems ok but when I go to any of these programmes the font is not there or comes out as blocks. I have even used spotlight to find out where it is ( I have been moving it between system /library/fonts and library/fonts) - and it says it is a windows font! Why?

so will it work in any of the above programmes? and can I get a version to use in these progs?
