If you are unsure which version of InCopy you have you can find out by selecting the option "About InCopy" under the "Help" menu in the application. (This is found under the "InCopy CC" menu on a Mac.)
This will then display the version and version number:
In versions later than CC2017 only the version number is displayed.
CC2018 is version 13
CC2019 is version 14
The version is also shown at the top of the application window if you are using a Mac:
If you need to install a version you do not have please see the page here.
