I have PowerPoint presentation in Arabic but they don't show correctly on my MacBook Pro. It shows Arabic letters scattered and I can't find Arabic Fonts. I'm using the computer mostly in English.
Windows 7
Try selecting the text and switching to Geeza pro or one of the other Arabic fonts that come with OS X: Al Bayan, Baghdad, Nadeem, DecoType Naskh, Lucida Grande, Damascus.
But Office for Mac has poor support for Arabic, Word cannot do it at all. You may need to use another app like OpenOffice or Keynote. Keynote has bad Arabic bugs too.
For problems with MS products, best use their own forums:
