I still regularly (or did) use older versions of InDesign. Version 2014 particularly as it is more stable and I have some scripts that work with it. I recently decided to update creative Cloud and to install the latest version. But it did not ask me if I wanted to uninstall earlier versions and went ahead and did so. Is there a way to undo this or reinstall version 2014 at least?
They are buried in your CC application
For future reference, the option to not delete previous versions is still hidden under the Advanced tab in the update panel, and the default is to remove them (despite many user complaints about this). The fact that they will be deleted is mentioned in the small gray text, but many people don't notice this before proceeding.
