Error System.ObjectDisposedException VSTO SmartTag?

I'm having trouble getting a vsto project to work. It's a simple Word 2007 addin application that adds a smarttag identifier.

here's the error:

****开发者_高级运维********** Exception Text **************
System.ObjectDisposedException: Cannot access a disposed object.
   at Microsoft.Office.Tools.SmartTagCollection.BeginInit()

   at Microsoft.VisualStudio.Tools.Applications.AddInAdapter.ExecutePhase(ExecutionPhases executionPhases)
   at Microsoft.VisualStudio.Tools.Office.Internal.OfficeAddInAdapter.InitializeEntryPointsHelper()

somehow the smarttags are disposed? I don't get it.

Solution:

I knew this applicatio worked before so I published it. When I went to install the add in the install app required the VSTO 3.0 runtime SP1 update. The app requires the SP1 update.
