Winhlp32 is the only help file made available by Microsoft. You might find this useful reading: Windows Help Coming to Windows 7 RTM - Reveals Microsoft - Softpedia
The help file in the RTM 64Bit (which I am using ) points to a subfolder in the Window folder, containg 301 files and is 44mbs in size. As with Vista, you can also choose to link to Internet help.
But what is the app to which you refer?. Maybe someone can help you here.
The app is Ventura Publisher 10, an oldie but goody. The help in question is not Windows help but the extensive help files of Ventura. The Microsoft file winhlp32.exe is required in order to use the Ventura help. A downloadable version was made available for Vista, and one is promised for Win 7 after release. I was just asking if there is a prototype of the Win 7 version available for download and test with RC.
