I've been using Visual Studio 2012 RC with trial license with no problems. I purchased Visual Studio 2012 Professional yesterday, installed the latest version, and installed Update 1.

I have a solution/project I've been working on for many years. It has many migrations in it. I ran my first add-migration TableX_NewField and update-database -sourcemigration:TableX_PreviousNewField in this latest version.

They both ran with no problems.

Then I ran update-database -script -sourcemigration:TableX_PreviousNewField and received the following:

PM> update-database -script -sourcemigration:TableX_PreviousNewField

I've ran windows updates. Checked updates with NuGet. Restarted my computer. Still have error.
