Hi @Deborah32775572yps1,
Thank you for sharing the screen capture and the additional details!
Since the installation goes smoothly but doesn't update to the latest version, please try the following steps:
1. In the Creative Cloud desktop app, click on the triple dots (•••) next to InDesign again.
2. Look for the option labeled "Other Versions".
3. From there, you should see version 20.0 available for installation.

Let me know if this works or if you need further assistance!
Best,
Abhishek
Hi Abhishek,
I've solved the issue... I work for two diferent colleges. I logged out of one college and logged in two my other one, but for some reason InDesign still thought I was logged in to that same college. I noticed that when I launched the program. I logged out of InDesign which then asked me if I wanted to log out of all Adoibe apps. I said yes and when I logged in again, all of the upldates became available... thanks for your help!
Debbie
