17.1 Crashes - Not functional

they way to fix this is replace it with 17.2. It is now avaialble to me. So far no issues. 

Hello - sorry for  your issues

However, you haven't shared exactly what is happening so it makes the help in return a little bit generic

There has to be something local on your machine causing the issue.

It would be great if you could share your system specs:

RAM

Graphics Card

HD Space

Operating system

17.2 is rolling out - but it's not available everywhere yet.

If 17.1 is not behaving you can Rollback to a previous InDesign version

----------------------

However, before you do that

Try resetting your preferences:
The easiest way to reset everything is to delete the InDesign preferences: as soon as InDesign starts to boot hold down Shift, Alt, Ctrl (and Apple/Cmd if working on a Macintosh). A dialog will appear asking to delete the InDesign Preferences, select 'Yes' on this dialog.
