what is "instance feature only"? – Gennady Vanin Геннадий Ванин Aug 28 '10 at 7:25

As far as I know, SQL2008 (and R2) Enterprise won't install on a Workstation OS - only Server.

The only editions of SQL Server that will run on client OSs are Developer (which is only licensed for development and test) and Express. – Richard Aug 28 '10 at 9:42
