Install Zune 2.3 on Server 2008 x64
After a couple failed attempts and a bunch of swearing at the "The media for installation package couldn't be found. It might be incomplete or corrupt." error message, I ended up going through the required components, finding that "Windows Format SDK" requires Windows Media Player. After installing the Desktop feature in 2008, which incldues Windows Media player, the Zune install completed with no problems.
