Thanks Greg. I was building an installer with NSIS and needed to install the snapstick driver during the install on a Windows 7 machine. Ultimately, I was able to do it with dpinst.exe. This exe can only be found in the Windows Driver Kit 8.1. Microsoft took it out of the latest WDK. Also, note that there are two different versions of dpinst (32 bit and 64 bit).

Exec '$INSTDIR\Drivers\dpinst64.exe /a /sa /sw'

will install the drivers silently.
