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.

pDisplayName: a string that supplies the display name of an application that is associated with a driver package. DIFxAPI requires an application display name to inform a user which application is associated with a driver package. For example, if a user clicks on the Remove button of an Add or Remove Programs entry that was created by the DIFx tools to represent a driver package, the resulting user dialog box will list the display names of the applications that are associated with the driver package. 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.
