By way of preface, I have Acrobat DC installed. In the last few days each time I attempt to open a pdf document I get an "Update Required" message. It tells me to update my operating system, which I do. But that doesn't cure the problem. Tried talking to someone at Adobe and got hung up on for my troubles. So I hope someone can help me.
An additur to what I reported originally. I attempted to download and reinstall Acrobat DC and I keep getting a No Internet Connection message. I clearly have an internet connection or I would not be able to post this message.
Thank you for responding. I finally got through to someone at Adobe, who took control of my computer and spent 15-20 minutes getting things fixed. Apparently, what the error message (which had been saying I needed to update my Win 10 OS) was actually attempting to tell me that I needed to download and install the most recent version of Acrobat Pro DC (which I had assumed was regularly/automatically updated per my subscription) and that required using a different browser (Edge instead of Firefox) and downloading/installing a "special" installer file.
