- In the newly opened Preferences dialogue window, click on “Apps” on the left pane

4. Click on the three ellipses on the far right to Illustrator, then select "Other versions"
5. Choose to install an older Illustrator version
This way you will end up with two versions of Adobe Illustrator on your machine, one of which provides maximum Arabic support.
