Hi Jeremy,

Thank you. I already have CA19 in InstallExecuteSequence, and it is working fine. The issue I am having is for InstallUISequence, where the "Priveleged' is getting set (with UAC on) prior to evaluating the  condition.

When including the installation context with the installation launch conditions, use a Custom Action Type 19 in the InstallExecuteSequence table and make the custom action conditional upon the Privileged property. 
Do not use an action in the LaunchCondition table with a condition based on the AdminUser property or Privileged property.
