Can't get Balloon driver working on Win 2008R2 or Win7 64bit

Hi all!

I've been working with Proxmox V2.2 and have many Ubuntu VMs running with out issue but when I try to get the Memory Balloon drivers to work for ether Windows Server 2008R2 or Win7 64bit, I can't seem to get them working. :(

I've downloaded the latest ISO from Radhat (virtio-win-0.1-52.iso) and I'm able to get the VirtIO drivers for Network & Disk to work but not for the Balloon driver.

Anyone have any ideas?

Has anyone out there got them to work for this situation?

Thanks!
