EXE spawned via custom action during silent installation

[FrodoH]

Is there a way to discern if an EXE is launched from a custom action with a silent installation? That is, I launch an EXE through a custom action and I would like the EXE to know if the installer is running in silent mode without having to rebuild the installer. Is there an environment variable or MSI property that is inherited by child process that signals the installer is running in silent mode?

Hello,

The installer sets the UILevel property to the level of the user interface.

Let us know if that helped, otherwise give us more details about your specific scenario.

Best regards,
