To add to this here is what I've done:
- Disabled UAC
- Added everyone to "Log on as a Service"
- Ran install from both mounted ISO and from an extracted ISO located on the server.
- Uninstalled Antivirus (Forefront Endpoint Protection)
My current setup is this..
Windows 2008R2 VM, latest patches.
Server currently has these roles:
- SSO 5.1
- Inventory service 5.1
- vCenter 5.1
- Update manager 5.1
