Do you have a McAfee grant number? If so, you can download "Common UI 1.3", then install it to resolve the error above. You will probably find Common UI download under \Messaging and Web Security category.
Please try clicking on all of your available products and look for the Common UI 1.3 link. It's just an extension package. Your grant probably includes it. In the previous post, I specified one category where I've found it. You may find it in other category too but name should be same - Common UI. If you are still unable to find it, please call support or open a ticket online : http://support.mcafee.com
