DPInst (Driver Package Installer) is a driver installer supplied by Microsoft. It is the recommended way to create driver installers for Silabs drivers.
For any DIFx-compliant driver package (including the output of the AN220 Driver Customization Wizard, found here www.silabs.com/interface-appnotes), the DPInst installer executable can simply be dropped into the driver package and an INI file created to customize the installer behavior.
The behavior of the DPInst installer can be configured though either command line switches or through an INI file. These facilities can be used to do things like suppress the installer dialog box (quiet install), forcing install of older versions, and controlling the uninstall behavior.
