Sets a pointer to a callback function that is periodically called by DirectXSetup. The callback function can be used for setup progress notification and to implement a custom user interface for an application's setup program. For more information, see DirectXSetupCallbackFunction. If a setup program does not provide a callback function, DirectXSetupSetCallback is not invoked.
