I am using Acrobat Pro DC Version 2015.006.30244 on a Windows PC running Windows 7 Professional Service Pack 1. Any time I try to reduce file size, Acrobat stops working. This happens even on relatively small files, i.e., 5-10MB, that I'm trying to get down to a size that can be emailed more easily. How can I resolve this? Thanks.
It is possible the file is corrupted and you may have to recreate it and please check if its happening with other files too.
Also, please share a screenshot of any particular error that shows up.
Please mention the workflow you follow as well to help me understand the issue better,
