Error opening Help in Windows-based programs: "Feature not included" or "Help not supported"

If you are in an organization, does your organization deliver content in the .hlp format?

• 
  Can you modify the program or the contents so that they do not have to use WinHlp32.exe functionality? For example, can you convert the help content that is currently in the .hlp format to an alternative file format such as .chm, .html, or .xml?
  
• 
  Does your organization store .hlp files on an intranet site? Can you install these files locally instead?
  

How to enable macros on a single computer after you install WinHlp32.exe
After you install the WinHelp32.exe program that is discussed in this article, certain macros are disabled. For more information about this issue, see the "Known issues" section.

This section contains steps to re-enable these macros by modifying a registry key. If your computer is in a managed environment, do not follow these steps without first consulting with your IT department. IT departments may decide not to re-enable macros or they may decide to re-enable them by using group policies. IT departments should read this article in its entirety before you continue.

Warning This article offers information about how to work around issues that are caused by changes in this release of Windows Help. However, Microsoft makes no specific recommendations about which registry keys and which values are right for your unique environment. If you are in a managed environment, your IT department is the best judge of how to weigh the advantages of these workarounds against the risks of using them. The safer course is to use no registry workarounds at all.

Note To perform the steps in this task, you must be logged on to the computer by using an administrator account. By using an administrator account, you can make changes to your computer that you cannot make with any other account, such as a standard account.

To log on by using an administrator account, you must know the password for an administrator account on your computer. If you are performing these steps on your personal computer, you are likely already logged on by using an administrator account. If you are performing these steps on a computer at work, you might have to ask the system administrator for help.
