Installing the Provider
Installation is a easy as installaing any other module. Simply upload and install the provider through the regular extension wizard found under Host > Extensions
Note that the provider install uploads a file with an extension of .tdf to your DNN. This is the spell checker dictionary, unfortunately this is a restricted extension in DNN though, leading to a warning message during the installation process. You can safely ignore this message.
Also note that the extension package does not include the Telerik.Web.UI.dll. It is being expected that this dll is already in your DNN installation.
