HOW-TO
Add the Help file to VS.NET

SOLUTION
You can easily set the Telerik help to appear in VisualStudio .NET (the supported versions are VS.NET 2002, VS.NET 2003, VS.NET2005 and VS.NET 2008). Here are the steps to do this:

Install the help system root

1. Download the attached ZIP file named root.zip from the "Article Files" section below.
2. Extract this ZIP file into the following directory on your computer: C:\Program Files\Common Files\Telerik. You can overwrite any existing files if prompted.
3. Open the directory mentioned above and find a .bat file named reg_root.bat . Run this file. It will register the root of the Telerik help to the Visual Studio and MSDN namespaces.

Install the product help from the product's ZIP installation

1. Extract the product ZIP file.
2. This file contains a directory named /Help. This directory holds the product help files. There you will find also a .bat file named reg_TelerikProduct.bat where TelerikProduct is the name of the product you have. For Rad menu this file is called “reg_RadMenu.bat”. Run this file and it will register the product help to the help root. Now the help will be accessible through Visual Studio.
   Note: In case the batch file is missing, you can easily create your own or run the command directly from command prompt.
   Here is the right syntax you should use:
   
   H2Reg.exe -R -M "cmdfile=[TelerikProduct]_cmd.ini"
   
   where you should set the right “_cmd.ini” file name. The ini file should be in the /Help folder. Example for RadGrid help:
   H2Reg.exe -R -M"cmdfile=RadGrid50_cmd.ini”

Note: Visual Studio should NOT be running during the help registration. If Visual Studio is running, you will need to restart it after completing the above steps in order to browse the Telerik product help. In some rare cases you may find your MSDN library gone if Visual Studio was running during the registration. This is because the newly installed help is not properly merged with the existing help (and MSDN). A machine restart should fix this problem.
