We're having a rather odd issue where if the path to a PDF is linked within a Word or Excel document for example. It will open up the document in Reader DC and then close immediately. Now if you have Reader open already, it will open the document just fine. Adobe Reader DC is set as the default, but it still attempts to open the files within Adobe even if another program is set as default.
Crash or freeze
Hope you are doing well and sorry for the trouble. As described if the path to a PDF is linked within a Word or Excel document for example. It will open up the document in Reader DC and then close immediately
