HTML5 report viewer requires Kendo UI libraries Q3 2015 (2015.3.930) or higher - HTML5 viewer requirements
. Kendo UI Professional license is not required if you are only going to use the widgets for the needs of HTML5 Report Viewer. Telerik Reporting provides a JS file containing a subset of the used by default Kendo UI widgets - telerikReportViewer.kendo-x.x.x.x.min.js.
However, if you use Kendo UI for the rest of the application it will be required to upgrade to at least Kendo UI Q3 2015.
The oldest version of Newtonsoft.Json.dll we support is 188.8.131.52. Therefore, it is possible to use version 6.0. Still, we recommend getting the latest available via NuGet.
