Help file installation for GoDiagram Win 5.2.0.46 file not found after installation

After installing GoDiagram Win 5.2.0.46 - Cant seem to locate the help file.
Is it included with the install or is it necessary to load it from another location?

All the files are in the docs folder. Success may depend of what version of Visual Studio you are using. Microsoft has been pretty weak in the support for help files department.
