Novice user can't open a file due to missing plug-ins
I am a novice user and have a legal copy of InDesign. I got it for the sole purpose of opening a file that was professionally designed to make some small edits. When I try to open the file (indd extension), I get a message that I am missing plug-ins. I have no idea how to identify which plug ins I am missing, and also no idea of how to install them if I figure it out. My software is the newest version and has no new updates. Thank you.
