Has CCDA version 5.4 been blocked from sign-in?

We have been pushing out a basic CCDA app + Acrobat to our computer labs for a couple years now. The package is built around v5.4. As of this week though, users are getting the following message if they happen to open the CCDA:

Has "apps" version 5.4.5.550 been blocked from auto-upgrading due to its age?

We really need a method for enterprises to allow an upgrade to the CCDA without a user signing in, as this thread and this thread are asking about.

I do not want to be spending my valuable time making new CCDA packages. I want a means have the CCDA install, then upgrade itself without needing to be signed into by a user.
