EF June 2011 CTP Install, throws error on User Machine

I Installed Entity Framework June 2011 CTP and changed the target fram开发者_JAVA百科ework to "EF June 2011 CTP", it works well with my Win7 Dev Machine, but in virtual xp machine it throws this error.

System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.Entity, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

The system cannot find the file specified.File name: 'System.Data.Entity, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

Any help highly appreciated
