New installations require only the Windows Installer (MSI) file. The postinstall ZIP file is an overlay to bring older installations up to this release and is not needed if you're starting with this version.
For upgrade assistance, refer to https://spaces.internet2.edu/display/SHIB2/NativeSPWindowsUpgrade
Note: The postinstall package requires that you install the latest Microsoft C/C++ runtime libraries, which you will find below.
The "SDK" ZIP file below is not required for normal installations or upgrades, and is solely for use by developers working on extensions.
