My team recently updated across the board to CC 2018. The designers updated first to InDesign and the editors followed with the update to InCopy.
Immediately after installing InCopy CC 2018, I noticed the InDesign files on our server were appearing as CS 5.5 InDesign files. I contacted support about it, and the fix was to install InDesign on my computer and open all the design files and resave them. I didn't need to do that. As soon as InDesign was installed, all the files appeared as the newest versions. However, I immediately uninstalled InDesign because I'm an editor and don't need access to it. After uninstalling, all the files reverted back to CS 5.5 icons.
We haven't had any compatibility issues, but it is a future concern because my computer thinks they are CS 5.5 files. I would hate for an update to be made that would cause corruption because the new programs couldn't read the old file types.
I saw the InCopy update this morning and hoped the bug would be among the fixes, but it wasn't.
Does anyone know what's going on and have a solution other than installing a program I don't need just so my icons are the right file type?
This is not a bug. The operating system, especially Mac, only knows about the latest version installed.
But I've never had CS 5.5 installed on this computer.
Let's back up.
What version of InDesign/InCopy are installed? What operating system?
I'm currently running CC 2018 InCopy only, no InDesign on this machine. I updated to OS High Sierra in order to update from InCopy CC 2017.
Honestly, I wouldn’t worry about it. If the files open, that’s all that matters.
This seems to be a file association issue and Bob explained in detail. As per your file opening query, forward compatibility should not be an issue and you should be able to open files created in older version in a newer version app.
You can also try to change the default app to open these files to CC 2018 by checking the file info.
