To download InDesign CC in Chinese or Japanese, you'll need to navigate to your Creative Cloud Desktop app preferences, change the language, and install InDesign in that language. Full instructions on how to do this can be found in this article: Change the language setting of your Creative Cloud apps
After you've downloaded this version, you should have access to vertical character composition: Compose CJK characters in InDesign
Please let me know if you are still facing difficulties with getting vertical type tools to work correctly.
Hope this return address can reach you directly. I appreciate your time answering my question.
Frankly I did exactly what you told me twice at least: the first time was when I found a similar instruction online, and the second after the first time failed. You can see from the clip below I am using the Chinese version, BUT...
What should I do now? Uninstall and try again? Thank you for your further suggestion.
There is no clip below in your posting. To insert a photo or video, you just come to the forum and use the buttons on the forum editor.
Sorry didn't notice that for I sent the reply from within an Email client.
Before taking any further action, You might notice as shown below that even the UI language is Chinese, there is NO vertical text tool.
So I moved on to the steps as below
1) change the lan of APP
2) and install InDesign. You might see that the UI language is still Chinese even I changed the APP lan to Japanese!
3) Run it. DONE!
Hope this is helpful to the people who encountered the same problem.
