Thomas Budge Posted March 4, 2021 Report Share Posted March 4, 2021 I have also recently been getting the same message. It pops up every time I wish to open a PDF file. If I then press ESC or click on OK button, the requested file opens correctly. My version number is: 12.16.3.574 I was about to uninstall/reinstall but I shall wait for a response. Thanks.
