Answer 1

I had this error in Visual Studio 2013, with an SSIS project. I set Project, Properties, Debugging, Run64BitRuntime = false and then the SSIS package ran. However, when I deployed the package to the server I had to set the value to true (Server is 64 bit Windows 2012 / Sql 2014 ).

I think the reasoning behind this is that Visual Studio is a 32 bit application.
