    Hello Aron,

    This is a generic error and usually means that there is a mismatch in your referenced dll and the actual one used. Most likely you have not uninstalled previous reporting installations and have mismatched references. Please use the Upgrade Wizard to upgrade your projects containing Telerik reports and rebuild the project. If you have added manual references i.e. Copy Local = True, then delete all assemblies from bin folder, re-add proper references in the project and rebuild the project after that.

    Best wishes,
