Failed to clone windows xp or 2003 in Vcenter 4.1

I've recently upgraded to Vcenter 4.1 and upgrade all our hosts. Now i’m having trouble with creating xp or 2003 VM's from templates using the customization specifications Manager (Windows7,2008, 2008R2 work fine).  After I deploy the Clone Virtual Machine task fails at 93% with the details of "Customizing the new Virtual Machine"

I have extracted the correct .cab files into the correct folders as per kb.vmware.com/kb/1005593

I've done with before with ESX3.5 and 4.0 and it worked fine, it's just when I've upgraded to 4.1 that I’m having trouble. I'm not sure if this matter but I also have Vcenter running on 2008 R2.
