Ever since getting Adobe Acrobat DC Pro (version 2019.010.20100) on a new Windows 10 64-bit Enterprise client , any time I open a PDF to do anything (edit, PDF, Organize Pages, or just leave the PDF open without selecting any tool), I have about 45 seconds before Acrobat locks up and is unresponsive. Every time I have to close the program. I have to go to another workstation running Windows 7 Professional SP1 and use Acrobat Pro 2015.006.30456, which runs flawlessly. Do I have to make a request to roll my machine back to Windows 7 in order to solve this problem, or are you ever going to do something about this?? You have known about this problem on Windows 10 64-bit OS, documented in multiple forums, since September 2017. It is completely unusable, and my company is paying you money for this garbage software subscription. What is your team doing about this?!?
