Marhaba Tarek, I don't have a problem with Acrobat, check my post # 8 above were I posted a "solution", well at least I think it's a solution.
Thank you Zaid Al Hilali!
I think the problem is resulted the the OS Language/Regional Settings on the Windows PC.
On my personal Laptop (Windows 10), I have set Arabic Language based settings in several places. However, the main UI is English. If I remember correctly, such settings are in Regional Options or something like that.
On my Work PC (Windows 7), there is no problem, and all such related Languages settings are based on English.
All other Acrobat settings/preferences are exactly the same on both personal laptop and work PC.
Following is the main place where I need to verify. Below is snapshot of my Work PC Regional and Language Settings for System Locale. When I am back home, I will try to play around with such configurations to see if this will make a difference. This includes Format, Location, Keyboards and Languages, and Administrative.

Regards,
Tarek
