pApplicationId: a string that supplies a vendor-defined token. DIFxAPI uses this token to associate an application with the driver package. This token should be a unique application-specific value, such as a GUID. DIFxAPI does not enforce uniqueness among the tokens. If a caller supplies an INSTALLERINFO structure that specifies an association between an application and a driver package, this member must not be NULL or supply an empty string.
