See if you have a "warning" message stating "Cannot generate deployment plan due to an internal error". If so, the Update and Generate Script buttons will be disabled.

Close Visual Studio, navigate to the folder containing the Database project and remove all (*.dbmdl) files. Then restart Visual Studio, re-run the compare schema at which point the Update button should be enabled.
