Arabic font problem in Adobe Reader

I had this problem in Adobe Reader when opening a file that contains some arabic text.
"Cannot find of create the font 'Arabic Transparent Bold'. Some characters may not display or print correctly."

I went to the adobe website, and got the language pack from here, but it didn't solve the problem, as this pack doesn't contain the transparent font.
Here is the solution
1. Go to this site: http://www.websrilanka.com/Download%20Fonts/
2. download the files
simpo.ttf
simpbdo.ttf
simpfxo.ttf
artro.ttf
artrbdo.ttf
3. double-click each one, and click the "Install" button at the top of the window. Note that you will have to do it for each and every file.

 Note also that you can find these fonts in other places, just google the names.
