Hi,
I assume you are running a Windows computer. Can you share the exact version of your software and operating system.
I would recommend that you check the EventViewer (there is an equivalent for Mac using Console).
Every 'crash' should be listed there with additional details of what conflicts with your software start.
Also, When unsintalling an Adobe software, I would recommend to also use Adobe CC Clean to scrub any 'leftovers' in your system, turn off your antivirus before reinstalling Acrobat, then trun it back on.
Please remember to backup your computer completely first, just in case.
