Download the installer here: 

The latest version of the control only supports .NET framework version 4.0 and later and the installer only supports Visual Studio 2010 and later.

After installing the controls should be visible in the toolbox. If not, then you can manually add “Guifreaks.Navisuite” to the toolbox. Design time functionality only works when Guifreaks.Design, Guifreaks.Common and Guifreaks.Navisuite assemblies are available in the GAC. The installer installs the DLL’s to the GAC. If design time functionality is not working, use GACUTIL to add them manually to the GAC.
