I have a Win 10 Pro pc, with Adobe Acrobat 2017 Standard. Initially, there was a problem previewing Excel and Word attachments in Outlook. This was resolved by uninstalling and reinstalling Office 2016. After that, I noticed that I was no longer able to save Office documents as pdf files. To fix this, I had to uninstall and reinstall Adobe Acrobat 2017. Since then, I have been unable to directly open PDF files that are located in shared drive folders from our server. This is the error: "There was an error opening this document. This file cannot be found." If I do a file open from within Adobe, and search by using a UNC path, the pdf files open with no problem. Adobe Acrobat is set as the default program for opening pdf files on the pc. I have tried running as administrator, and running under compatibiloity mode, with no difference.
