FastHelp is developed under Windows 10 and works with all versions of Windows and Vista including the latest version 10, while retaining backwards compatibility with XP, Windows 2000, Windows 2003/8 Server and Windows 95.
Say goodbye to WinHelp
Microsoft decided to drop support for WinHelp in Vista. WinHelp was last updated in 1997, so it is ancient in computing terms, but is still used in many programs. With Windows 7 Microsoft decided to allow WinHelp support but you need to install it manually. Please go to the link below to download WinHelp support for your specific operating system.
FastHelp will still compile to WinHelp, but you will not be able to view your HLP files on Vista, Windows 7, 8 or Windows 10 without installing the support for it first.
The recommended alternative to WinHelp is HtmlHelp, i.e. CHM files. Because FastHelp is a single-source editor, you can simply compile to any of the 7 compile formats. This will also be the same with any new compile formats that we add, thereby protecting your investment in your help text.
Turning on WinHelp Options under Vista, Windows 7, 8 and Windows 10
FastHelp will automatically hide WinHelp options under Vista, Windows 7, 8 and Windows 10, but you can enable them from the "Project Settings" screen by checking the "Show WinHelp Options under Vista, Windows 7 or Windows 8" option.
