Adobe provides perfect solutions for enterprise deployment. If you deploy software like Adobe Reader in an environment with 100's or 1000's of users without disabling the automated update feature you should think about your software deployment strategy or it is a lack of knowledge.
The provided updates may be security relavant, espacially for Flash Player. Even if there would be a way to install updates without administrative rights, how would you control that users are installing it and not skipping it forever?
So the strategy is disabling automated updates, which is supported in all Adobe products I have to work with and deploy the updates in your environment using SCCM or something.
