You can upgrade your Adobe Technical Communication Suite to the latest version (2017 release) if you have an active subscription of Adobe Technical Communication Suite.
Ensure that both the files (.7z and .exe) are saved in the same folder.
If you do not save the files in the same folder, an error message appears during the installation. For example, "Windows cannot open this file" or "The file archive part of Adobe [product name] is missing."
Sign in using your Adobe ID that you used to purchase the Adobe Technical Communication Suite subscription.
For any issue related to your Adobe ID, see Adobe ID account and sign-in troubleshooting.
