Yes Fred,
SET HELP is ON, SET HELP TO (path and name to may Help.CHM is corect).
But I forget to say that I use Install-us Pro to SetUp my application. I install all files needed to run HTML Help (Hh.exe, Itircl.DLL, Itss.DLL, HhCtrl.OCX) but , like I said nothing happens. When I use Setup Wizard and install only HTML Help engine (no application or other) Help begin works perfect. May be I not install some files, or not register them (ActiveX controls HhCtrl.OCX I register). Can You give me some advise what I must do ?
