Can't use virtual appliance mode

[fjones]

I recently downloaded the 4.1.1 eval and I am currently testing by running it in a 2003 server VM on a Vsphere 4 host. I have a licensed (Essentials) Vsphere ESX host.

I am able to backup in VMware VStorage API "network" mode but not in "Virtual Appliance" mode. The Vsphere Client gives the following errors:

The Vsphere client "Status" error shows: "There are insufficient licenses to complete this operation" and when I click on "View Details" it says "There are insufficient licenses to complete this operation. Feature hotplug not licensed, requires need have have"

What type of license does "Virtual Appliance" mode require? Or am I missing something?

Thanks.

Frank, do you have latest vSphere version (Update 1)?

That was it. Once I upgraded to update 1 it worked beautifully.
