DIFxApp Configuration Flags (MSI)

Flag values for the DIFxApp merge module, to use in the MSIDriverPackages table when installing drivers in a MSI file. Remember to add the DIFxApp merge module, otherwise the driver will not be installed in the DriverStore.

This method is equivalent to DPinst.exe with a lot of switches.

Flag Description
1 Force driver installation
2 Suppress a prompt to connect a device
4 Suppress the creation of a Programs and Features entry for a driver package
8 Install an unsigned driver package
16 Remove installed files

Happy package building.
