Hello, I need to know how I can update my CC version to CC 10.0 to open a document create by 10.0? The system says: "cannot open this file, because it was saved with a newer version of Adobe InDesign CC(10.0). You must use that version or later to open the file. To then enable it to be opened in this version, choose save as Indesign CS4 or later, or export to IDML. "@
version 10 is CC 2014, and if your hardware will support it you can download and install it as part of your CC subscription. If after updating the the desktop app you don't see the new versions listed in the apps tab your OS may be too old.
