How do I allow the intstallation of specific Active X Controls through Group Policy?

We have a server that periodically goes through updates. When it updates certain core applications we have to install a new Active X control on every machine. I have tried to allow this behavior automatically via Group Policy. I did the following:

1. I made sure that all permutations of the servers address were added to Group Policy and set to put that IP and DNS name into the Trusted Sites Zone.
2. For the Trusted Sites Zone I cut off automatic prompting. Enabled the download of signed Active X controls and unsigned Active X controls. Set it to enable the running of Active X controls and plugins. Also set it to script the Active X controls marked safe for scripting.

Despite verifying the above was properly set via Group Policy Modeling, they still will not automatically update. I understand that it is likely a permission issue on either a folder or the system. If so, what is the specific permission that would need to be granted to allow this update to install seamlessly and automatically. As it is we have to touch EVERY PC as an Admin to install the new settings. The server shows up in Trusted Sites, so what am I doing wrong?
