To install Adobe InCopy CC 2019 (which is version 14) you will need a Creative Cloud account (with a paid subscription for InCopy) as well as the "Creative Cloud Desktop App". For more information about Creative Cloud licensing please see the information here. The "Creative Cloud Desktop App" can be downloaded here.
IMPORTANT: You must have CtrlPrint Transfer Manager (1.3.2 for Windows and 1.3.3 for Mac) to use CC2019. See the links for installing and updating Transfer Manager here.
If you are trying to use Adobe's Creative Cloud Packager for installing CC 2019 please use the information here.
1. Once the "Creative Cloud Desktop App" is open locate InCopy. Click on the "..." icon and choose "Other versions".
2. Locate "InCopy (14.0)" and click "Install". (Note that this number may be higher if updates have been performed by Adobe (as seen below). However it will begin with "14".)
3. InCopy CC2019 (v 14) will now install.
If the download option is labelled "Try" it is because you are not logged in with an Adobe account with an active subscription for InCopy. You can still install InCopy as a free trial for 7 days, however after this time has expired you will need a subscription.
