SP_ALTPLATFORM_INFO_V2 structure (setupapi.h)

The SP_ALTPLATFORM_INFO_V2 structure is used to pass information for an alternate platform to SetupQueryInfOriginalFileInformation.

Setup uses the SP_ALTPLATFORM_INFO_V2 structure if USE_SP_ALTPLATFORM_INFO_V1 is 0 or undefined and _WIN32_WINNT is set to 0x501. FirstValidatedMajorVersion and FirstValidatedMinorVersion are only available with SP_ALTPLATFORM_INFO_V2 and for use with Windows Server 2008, Windows Vista, Windows Server 2003, or Windows XP.

Setup uses the SP_ALTPLATFORM_INFO_V1 structure if USE_SP_ALTPLATFORM_INFO_V1 is set to 1 or if _WIN32_WINNT is less than or equal to 0x500. FirstValidatedMajorVersion and FirstValidatedMinorVersion are not available with SP_ALTPLATFORM_INFO_V1.

Members

cbSize

Size of this structure, in bytes.

Platform

Operating system. This member must be one of the following values.

MajorVersion

Major version of the operating system.

MinorVersion

Minor version of the operating system.

ProcessorArchitecture

Processor architecture. This must be PROCESSOR_ARCHITECTURE_INTEL, PROCESSOR_ARCHITECTURE_ALPHA, PROCESSOR_ARCHITECTURE_IA64, PROCESSOR_ARCHITECTURE_ALPHA64.

DUMMYUNIONNAME

DUMMYUNIONNAME.Reserved

DUMMYUNIONNAME.Flags

For Windows Server 2008, Windows Vista, Windows Server 2003, or Windows XP, this member must be set to SP_ALTPLATFORM_FLAGS_VERSION_RANGE to use FirstValidatedMajorVersion and FirstValidatedMinorVersion. This member must be set to zero for Windows 2000.

FirstValidatedMajorVersion

Major version of the oldest previous operating system for which this package's digital signature is valid. For example, if the alternate platform is VER_PLATFORM_WIN32_NT, version 5.1, and you want a driver package signed with a 5.0 osattr to also be valid, set MajorVersion to 5, MinorVersion to 1, FirstValidatedMajorVersion to 5, and FirstValidatedMinorVersion 0. To validate packages signed for any previous operating system, specify 0 for these fields. To only validate against the target alternate platform, specify the same values as those in the MajorVersion and MinorVersion fields. Available with Windows XP or later only. The Flags member must be set to SP_ALTPLATFORM_FLAGS_VERSION_RANGE to use FirstValidatedMajorVersion.

FirstValidatedMinorVersion

Minor version of the oldest previous operating system for which this package's digital signature is valid. For information see FirstValidatedMajorVersion. Available with Windows Server 2003 or Windows XP. The Flags member must be set to SP_ALTPLATFORM_FLAGS_VERSION_RANGE to use FirstValidatedMinorVersion.
