I have Miscrosoft Office Standard 2007 where I installed to 3 Vista machines. The 2 machines were OK but the other machine keeps receiving a Configuration Wizard everytime he opens a doc & excel file. And I looked at the Event Viewer, I saw the warning "A provider, OffProv12, has been registered in the Windows Management Instrumentation namespace Root\MSAPPS12 to use the LocalSystem account. This account is privileged and the provider may cause a security violation if it does not correctly impersonate user requests."

I am not sure exactly what fixed the issue, I did not re-install Office 2007, what I did were the following:

  1. Change the WMI -> Msapps12 & CIMV2 security by adding the local user account to have full access.
    To access your WMI, type wmimgmt.msc from Start Search. Once open right-click to WMI Control (Local) then select Properties.
    Right-click to CIMV2 & MSAPPS12 then click Security tab. Add the local user account (not the administrator) and designate it with full control.


  2. Update Office 2007 to Service Pack 2
