This registry setting allows you to override the default viewer application used by MS Help Viewer (AKA Help 3) and VS 2010 IDE. Example 1: Set H3Viewer as the default viewer HKLM\Software\Microsoft\Help\v1.0
HelpViewerProgID=c:\program files\Helpware\H3Viewer\H3Viewer.exe
Example 2: Set Google Chrome as the default viewer HKLM\Software\Microsoft\Help\v1.0
HelpViewerProgID=c:\Users\Robert\AppData\local\Google\Chrome\Application\chrome.exe
Normally when you (or VS 2010) ShellExecutes a ms-xhelp:/// help URL, HelpLibAgent.exe runs and launches the help in the defined browser.
Set this registry item to specify a different browser or viewer application to run.
In example 1 we specify that H3Viewer.exe is the default viewer. In example 2 we specify that Google Chrome is the default viewer (the path is for Chrome 4.x on a Windows 7 PC). Note: Restart HelpLibAgent.exe once you change this setting.- To stop Agent right-click the Help Library Agent icon in the taskbar notification tray and select Exit.
- To start Agent run "c:\program files\Microsoft Help Viewer\v1.0\HelpLibAgent.exe" <no parameters>
Note #1: In the RC release there is a bug where Agent wont startup if Help Library Manager is set to "Online" mode. Try setting to "Local (Offline)" mode.
Note #2: You don't have to restart Agent for dedicated Help applications such as H3Viewer. They will start Agent when they need to.
