problems with idml for indesign cs5.5

[kyra_becker]

The idml file, that I exported from InDesign 2020 on MacOS Catalina for cs 5.5, is said to be crashed. On my old Mac, where cs 5.5 is still running, I manage at least to open the doc, but I can't save it, even not under a different name. Somebody has an idea? Is it a bug from the 8 days old InDesign 2020 Update?

thanx for your input and help 🙂

Perhaps you're using a feature which isn't available for CS 5.5, and InDesign is not behaving nicely when running into it... Could you test creating a new file in CS 5.5 with some simple content, open it in CC 2020, and immediately save it as IDML and try to re-open it in CS 5.5. If it fails, then it's not due to any specific content but it's the process being disturbed in general.
