Source msdn Fail to start project

For visual Studio 2013 execute the command cd "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\PrivateAssemblies" in point 2 and then execute point 3 and 4.

The following is the command we have to use to resolve the issue:

"C:\Program Files\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\gacutil.exe" /if "C:\Program Files\Microsoft Visual Studio 11.0\Common7\IDE\PrivateAssemblies\Microsoft.SqlServer.Dts.Design.dll"

Make sure that your dll file and Gacutil.exe file locations are correct. It may be different in other systems.

Note: You should open your “Command Prompt” as an administrator to run the above command.
