In recent work using Visual Studio 2012 creating SSIS packages, the following error was encountered:
I was able to temporarily solve this error using the following steps:
(1) Open the Developer Command Prompt in Visual Studio 2012 as Administrator.
Because the Developer Command Prompt wasn’t immediately visible on my Windows 8.1 system, some additional steps were required.
- Press the Window button on your system. In the Start window locate the Search field and type “Developer Command Prompt for VS2012”.
- Locate the Search result for the Developer Command Prompt, right-click, and select Pin to Start.
- Now right click on the Developer Command Prompt for VS2012 tile and select Run as Administrator.
- Select Yes if the User Account Control prompt appears.
(2) Execute the commands (note you can do this as a single command):
- cd C:\Program Files (x86)
- cd Microsoft Visual Studio 11.0
- cd Common7
- cd IDE
- cd PrivateAssemblies
With the execution of these commands, you should be located at
C:\Program Files (x86)\VisualStudio 11.0\Common7\IDE\PrivateAssemblies
(3) Execute the command gacutil /if Microsoft.SqlServer.Dts.Design.dll:
This loads the DLL to the Global Assembly Cache. It replaces the older DLL with the new one.
I continue to look for a more robust reason and ultimate fix on this issue. Once I locate it, I will augment this post with those findings.
The primary steps in this post, were obtained from the post Fail to Start Project.
