After adding a custom AddIn, I'm experiencing the following error message when trying to load it from a fresh install of ArcMap 10.3.1 on Windows server 2012 R2.
"The Type initializer for SmartSortDesktop.AddInconfiguration threw an exception. "
The same tool bar is working on another windows server 2008 R2.
Any suggestions to where i could start looking. New to this platform.
