Microsoft Help 2.x Compiler
Note: Because the only generally available viewer
for Microsoft Help 2.x files is included only with Visual Studio .NET, you should only use the Microsoft Help 2.x to compile documentation that
will be viewed from within the Visual Studio.NET IDE (e.g. for .NET
assemblies or Visual Studio .NET integrated products).
Visual Studio 2002 and 2003
For Visual Studio 2002 and 2003 users, the Microsoft Help 2.x Compiler is available as part of the Microsoft Visual Studio .NET Help Integration Kit, a Microsoft provided free Add-In to Visual Studio .NET that provides the functionality for compiling Microsoft Help 2.x projects.
You can freely download the Visual Studio .NET Help Integration kit from the MSDN downloads section
from the links below.
