@JoleneCampbell Hi, this does sound as though it is the update that is causing you problems if you can revert to a previous version with no issues. I updated to 16.3 (Windows) a few days ago and just tested exporting. I'm able to export a variety of documents to PDF without any problems. I'm curious to know if you crash on exporting any type of PDF preset or only with some. Have you tested it with various presets i.e., High Quality Print, Smallest File Size, or any of your own custom specifications? Also, is the point of crashing immediately after you hit the Export button? Or does it try to generate a PDF, get hung up, and then crash? I'm assuming you've reinstalled ID already. What about a preference reset? If the previous version is otherwise working for you, maybe stay with that version until until it is determined if this is a bug with more people or if it's only with you.

Oh, bless you!! I had already reinstalled both ID and Acrobat, to no avail. So I just reset the preferences. BINGO! That appears to have done the trick. Thank you so much. I was really going nuts.
