Novell ZENworks 10 Configuration Management with Support Pack 2 - 10.2
What is the difference between "Grant administrator privilege to user during installation " and "install elevated " for bundle install actions?
Install actions from bundles always set "install elevated " so that the Windows installer service has full rights.
Additionally, the action set to run as user can define "Grant administrator privilege to user during installation". This ensures that custom actions being run as user, requiring administrator rights, or specific checks by the MSI that the user is an administrator will not fail.
