InDesign no longer works

[meyej]

I have several Adobe Programs that stopped working after installing Catalina on my MAC. I am trying to use InDesign and it won't open.

What is the version of InDesign that you have installed on you MAC? What error do you get?

What version of Creative Cloud are you using? Only Creative Cloud programs that are CC 2019 or CC 2020 are supported for Catalina. More details about Catalina compatibility can be found at: https://helpx.adobe.com/x-productkb/global/fix-macos-64-bit-compatibility-errors.html.

Hi  MeyeJ:

If it turns out that you are on a older version of InDesign, here are instructions for rolling back your OS.  The rule of thumb is that if you don't want upgrade your software, don't update your OS.

If it turns out you are on a current version of InDesign, try rebuilding your cache/preferences.
