I have not seen this particular issue addressed for this error message, so I am opening a new thread.
I've been using Creative Cloud ID since 2013. I recently began receiving the "Either file does not exist…" message on a number of files when I double-click to open them directly in ID. These files were created very recently or years ago. Some have been modified and saved at various times through the years. Others were newly created in recent weeks. I am able open all of the files using all other menu or keyboard methods (Open, Open Recent, command-O) and also via Bridge. I have no problem working on or saving them once they are open, only opening them by double-clicking directly in ID. The files are from various, unrelated projects and are saved to various, unrelated folders. Meanwhile, all files from just one particular folder open directly using the double-click in ID with no problem!
What could be causing this? How can I rectify it?
Are you working on a Mac? Have you already tried getting info and changing the "open with" setting in the info panel?
Select the file icon for the InDesign Document, right click or do Cmnd+option+i for "get info" in that panel you will see an option for "open with". Select the version of InDesign you want. Note there is a "Change All" button there that will make that selection stick for all similar files so you wont have to do it for each individually.
Thanks, ethanbk, I will try that and let you know if that solves it.
