How do I install a hardware driver (inf file) using C++?
Platform : Win32
The process is usually called pre-installation. (The normal install process is triggered by the arrival of an hardware device.)
The relevant functions can be found in <DIFxAPI.h> from the DDK. You probably want to call DriverPackageInstall(). The expected return value is ERROR_NO_SUCH_DEVINST [sic] as there won t be such a device yet.
There s some 64 bit funkyness: you can t install a 64 bits driver from a Win32 app (at least not in XP/Vista/Windows7/2003/2008). Hence, your Win32 installer must check if DriverPackageInstall() returns ERROR_IN_WOW64 and then call CreateProcess to start your 64 bits installer.
I would look at using the InstallHinfSection function, in the setupapi.dll. Here s the related docs:
