And No you cannot use the ActiveX control, it's for use within Visual Studio only. None of our runtime redist packages include it.,
Search for KBA 2163438, it has a printer test app attached and needs CR for VS 13 runtime SP 15 or above to be able to use it.
CR Designer does not install.NET runtime like it used in CR 2008 and previous.
The basics are:
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
using CrystalDecisions.ReportSource;
using CrystalDecisions.Windows.Forms;
For Extended API's you need to use RAS:
using CrystalDecisions.ReportAppServer.XmlSerialize;
using CrystalDecisions.ReportAppServer;
using CrystalDecisions.ReportAppServer.ClientDoc;
using CrystalDecisions.ReportAppServer.Controllers;
using CrystalDecisions.ReportAppServer.ReportDefModel;
using CrystalDecisions.ReportAppServer.CommonControls;
using CrystalDecisions.ReportAppServer.CommLayer;
using CrystalDecisions.ReportAppServer.CommonObjectModel;
using CrystalDecisions.ReportAppServer.ObjectFactory;
using CrystalDecisions.ReportAppServer.Prompting;
using CrystalDecisions.ReportAppServer.DataSetConversion;
using CrystalDecisions.ReportAppServer.DataDefModel;
using CrystalDecisions.ReportAppServer.XmlSerialize;
