I have SQL Server 2012, SSIS, SSDT and Visual Studio 2010. I can create a new SSIS package and add a Script Task, but if I attempt to open the Script Editor for that Script Task I get the following error:

TITLE: Microsoft Visual Studio
------------------------------

Cannot show Visual Studio 2010 Tools for Applications editor.

------------------------------
ADDITIONAL INFORMATION:

Could not load file or assembly 'Microsoft.VisualStudio.Tools.Applications.Core, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. (mscorlib)

------------------------------
BUTTONS:

OK

From my own investigation into this error, I found that Visual Studio Tools for Applications appears to be a part of MS Office 2007 and higher. This seemed like an odd dependency for to have, but I installed MS Office 2010 just for grins. It didn’t change anything. What else should I try?

    I figured out my problem this morning. When I uninstalled SQL Server 2012 (and the remnants of 2008 left behind when I upgraded last month) I also uninstalled 3 packages that were actually part of Visual Studio 2010. Had I not done this, a reinstallation of SQL Server 2012 would probably have done the trick, but instead I found new errors. When I reinstalled these 3 packages from the Visual Studio 2010 distribution media, everything started working.

    The 3 packages in question were:

    • Microsoft SQL Server 2008 R2 Data-tier Application Project
    • Microsoft SQL Server 2008 R2 Data-tier Application Framework
    • Microsoft SQL Server 2008 R2 Transact-SQL Language Service
