I've seen a thread about this before, from a few different folks, but I haven't seen a satsifying answer. If I've missed it, please reply with a link to that thread.
I get this message when I try to save a document I'm working on:
While doing a saveas does work, it's a nuisance to have to keep making new files. It's not open in any other program: I will receive this message even when I only have InDesign open, with just one file open in InDesign.
I'm running Windows 10, but this happened to me frequently on Windows 7 as well.
I'm running the most updated version of InDesign as of 2/1/2016.
This happens on all files, at random, not just one or two.
Any help? Here's the same question from October 2014: https://forums.adobe.com/thread/1591435#expires_in=86399993&token_type=bearer&access_token =eyJhbGciOiJSUzI1NiIsIng1dSI6I…
Perhaps a shot in the dark, but try this:
And be sure you really have write permission for the file and folder where you are trying to save.
