You can download the HtmlHelp compilers as part of the
VS
2005 SDK (formally VSIP).
Once you have downloaded them,
expand the file to a folder using WinZip or similar (WinZip knows it's a
Winzip compressed exe).
Download the file patch_vsip_setup.msi.zipand
use winzip to extract its contents (xxx.vbs) to the folder you extracted
the VSHIK to.
Run the patch_vshik_setup.msi.vbs which patches the installation. An
OK message box should appear if successful, otherwise there will be some
error message.
install the VS 2005 SDK. When you've done this,
GenHelp will be able to find the
compiler.
