There are a few differences between HTML Help and WebHelp that you should consider before choosing your online help output solution.

HTML Help is limited in that it only runs on 32-bit Windows systems and it only works with Internet Explorer. However, the files do not run over the internet. They must be downloaded and run locally using Internet Explorer as the viewer. An advantage or disadvantage, depending on your application of the online help system is that HTML Help is complied and compressed before it can be deployed. A .CHM file is generated after the help system is compiled and is installed on the system when the application installation is performed.

WebHelp can be accessed from many platforms and works with Internet Explorer, Netscape Navigator, and Mozilla Firefox. The can be run locally or viewed using the internet. To view the online help system using the internet, the .HTM files are deployed to a folder on the Web server where the web application is also installed.
