Sounds like you might be getting a missing or out of date plugin error when you try to open a file. That's indicative that the file was saved in a newer version of ID than the one you are using. Can you tell us more?
You should always inform us on:
- In your case localization
I suppose you have InDesign from the Creative Cloud. You can change the language in the CC app to something else than a Western language (English, German, Russian, Greek, etc.) to e.g. Hebrew and Arabic. Then restart the CC app. Then install InDesign with Hebrew or Arabic. Change the language back in the CC app again to your normal language.
When you now start InDesign you will find the World Ready Composer in the Justification section in Paragraph Styles.
Thank you, I’ll try that ;-)
