Since I didn't have routes in the firewall for the new subnets which are part of this NAC project this update process didn't work.
Here's the answer:
A variety of updates are available from the Clean Access Updates server, available under Device Management > Clean Access > Updates. You can perform updates manually as desired or schedule them to be performed automatically:
Cisco Checks and Rules
Cisco provides a variety of pre-configured rules ("pr_") and checks ("pc_") for standard client checks such as hotfixes, Windows update, and various antivirus software packages. Cisco checks and rules are a convenient starting point if you need to manually create your own custom checks and rules.
Supported AV/AS Product List
This list is a versioned XML file distributed from a centralized update server that provides the most current matrix of supported AV and AS vendors and product versions used to configure AV or AS Rules and AV or AS Definition Update requirements. This list is updated regularly to add support for new products. Note that the list provides version information only. When the CAM downloads the Supported AV/AS Product List it is downloading the information about what the latest versions are for AV/AS products; it is not downloading actual patch files or virus definition files. Based on this information, the Agent can then trigger the native AV/AS application to perform updates. For the latest details on products and versions supported, see Device Management > Clean Access > Clean Access Agent > Rules > AV/AS Support Info, or see the "Clean Access Supported Antivirus/Antispyware Product List" in the latest latest release notes.
