  • Thanks Oussama . This was not the issue that I was having but it did point me in the right direction. My Win 7 machine is not using  the virtual machine option.  This has been disabled.  I found by  problem to be with the registry settings "HKLM\SOFTWARE\Microsoft\Windows NT\Current Version",  “BuildLab” =  “7601.win7sp1_rtm.101119-1850”.  The expected value for this setting is “7601.win7sp1-gdr.110622-1506”.   Making this change resolved my issue.  Thanks.
