This has been disabled by a Microsoft patch due to security reasons 
regarding compiled html help on network shares some years ago.
You can re-enable it according to Microsoft documentation with the 
following registry settings (which make your system more less secure):

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\HHRestrictions]
"EnableFrameNavigationInSafeMode"=dword:00000001


You can also choose to use another help format bin R such as html help.
