Have you thought of installing the Middle Eastern (ME) version of Illustrator to finish this Arabic project? You know you can keep the existing copy of Illustrator, while using the ME version for any Arabic projects.

1. In your Adobe Creative Cloud application, access your account found on the top-right corner.
2. In the pop-up window (your account) click the "Apps" option on the left pane

6. Click "Install" for the version you've selected
