Hi Malko59,
I'm guessing that what you'd like to do is test that the
HHActiveX.dll is installed before the user tries to run the help?
Because, the easiest way for the user to test whether the
.dll is installed is run the help and look for the browse sequences
in the toolbar or a glossary (if you use one).
If you need to double check that the HHActiveX.dll is
installed, I'd chat with the programmers the run the script to
install it and register it (the registering bit is very important
as the .dll does not work without being registered on the end
user's PC), ask them to run a check to see if the HHActiveX.dll is
indeed registerer.
Check
http://www.developerfusion.co.uk/show/3479/
which provides some code for the developer for example. Or they
could perhaps run a search on the registry after the install - bit
over the top though if the code has been written well and tested.
Hope this helps more than a chocolate coffee pot
