Error using SolidWorks C# addin.

The swcsharpaddin.zip is in the location C:\Users\user\Documents\Visual Studio 2010\Templates\ProjectTemplates\Visual C#.

This is the error I get. I've not been able to get the SW API stuff to play nice with Visual Studio for the life of me- could someone help me out?

I'm using SW 2013.
