HI usureka
Unfortunately, it's not as simple as just having the .DLL
present. You will also need to have it
registered with Windows. If you look in the RoboHelp help
system, there are instructions for how to register the file. They
say:
Registering HHActiveX.DLL
This information applies to Microsoft HTML Help projects.
If your Microsoft HTML Help project includes an online
glossary, browse sequences, or WebSearch, a special file named
HHActiveX.DLL needs to be registered on end users' systems to
support these features.
The following steps help you distribute HHActiveX.DLL to your
end users and manually install HHActiveX.DLL, if necessary.
To distribute HHActiveX.DLL:
Open Windows Explorer and browse to your RoboHelp program
files folder (by default, this is located in C:\Program
Files\RoboHELP Office\RoboHTML).
Right-click HHActiveX.DLL and select Copy.
Browse to the location of your .CHM file and paste
HHActiveX.DLL into the same folder.
Distribute HHActiveX.DLL with your .CHM file and any other
files you are distributing with your Help system.
To manually register HHActiveX.DLL:You can provide these
instructions to your end users if you are distributing
HHActiveX.DLL with your Help system.
Click the Windows Start button, then select Run.
In Open, type the following:
regsvr32 <path> hhactivex.dll (specify the path of the
HHActiveX.DLL)
Click OK.
Tips:
You only need to distribute HHActiveX.DLL if you are
distributing a Microsoft HTML Help system that includes an online
glossary, browse sequences, or WebSearch.
