After making sure InDesign 2024 worked (not the newest computer), I removed previous versions, yes.
I did not delete the preferences for previous versions (there were issues getting INDD 2024 to port them over to the new version) -- until I read your post this morning. Did so, and rebooted the computer. That did not solve it. Am on production deadlines, so it will be a couple of days before I can try removing INDD 2024, rebooting, and reinstalling it. That will be my next move.
