Fixed a bug where XSP would fail to launch when using .NET 4 configuration on Windows. Path generator would generate the correct path, and then switch it out for the 4.5 library path instead. XSP isn't packaged into that directory on Windows, so MonoDevelop would throw an exception when it couldn't find it
