Hi,

     when i load my addin i get this error : Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without                                                            additional configuration information.

     The problem started after I have installed the service pack 2.0 of SolidWorks 2013.

     Attached "“SLDWORKS.exe.config”" that i have placed in my SolidWorks installation folder.

Best regards.
