Installation of the Visual Studio® help system

The local TwinCAT 3 Information System is installed in the Visual Studio® help system (Microsoft Help Viewer). Depending on the Visual Studio® version, the Visual Studio® help system is either an integral part of Visual Studio® or it has to be installed separately.
