These errors occur if you try to activate the app on more than two computers. An Adobe Creative Cloud membership lets you activate your apps on two computers. To activate your apps on a third computer, sign out of the app on one of the first two computers. Signing out deactivates all installed Creative Cloud apps and services associated with your Adobe ID on that computer.
To resolve the error and continue using the app on the current computer, try the following solutions.
This option lets you sign out of the app on all other computers. You can use this option remotely, without necessarily having access to the other computers. It's a good option to use if you lost the other computer or you accidentally uninstalled the app without signing out first.
