If the machine is in a workgroup, you need to place a . (dot) within the domein field.
Windows Vista 64 bit is a supported platform for all supported agents (so 3.6 or higher)
If you just want to upgrade the agents from machines that are already managed, you can also create a Client Task, that will install the McAfee Agent.
The client task will upgrade the agent for you.
