It think I had written a reply to this topic, but I will write it again
First you have to know that after Windows 98 Microsoft had changed its politics in producing Windows, how ?
they began to add all the famous language on the Windows, so that means the arabic language is available with Windows XP, but what is the problem ?
the problem is that the user usually forget to activate the Arabic language on the Installing process, so I think you have got to Install Windows XP and activate the ( Arabic Languae )
I hope that I had made something for you,,,,,
Good Luck !!
