--- Comment #6 from Alistair Leslie-Hughes leslie_alistair@hotmail.com 2013-02-09 18:38:23 CST --- When the setup100.exe is executed, mono attempt to load a library "Microsoft.SqlServer.Chainer.Setup" to find class "Microsoft.SqlServer.Chainer.Setup.Setup.Main" but this class lives in setup100.exe.
If you use the WINE_MONO_TRACE=all you will see mono attempting to load the library above.
