OpenStudioModelCorePINVOKE Issue

I am having the “Solution exception:The type initializer for ‘OpenStudio.OpenStudioModelCorePINVOKE’ threw an exception.” error after weeks of trying to fix based on other message board posts. Starting from scratch again with a clean OpenStudio install. Any advice on what to do next?

Uninstall your current OpenStudio and install OpenStudio 2.9.1
