check if MS Help 2 Runtime exists   

Hello,

I want to make our installation to check if there is a valid Help 2 runtime 
installed. Does anybody know if this is possible?

Thank you,
Niky

Re: check if MS Help 2 Runtime exists   

Hi,

    Maybe this is not the best form, but i know.only this method.

     You can check if runtime exists, creating a instance of object
"DExplore.AppObj.7" (COM Interface of dexplore.exe)
     This example you can use in C#, VB.NET e VB x or other languange what
work with COM Interface

        Ex:.

            Dim Viewer as Object

            Try

                viewer = CreateObject("DExplore.AppObj.7")

            Catch ex as exception

                    'HERE YOU CAN HANDLE THE EXCEPTION

            End Try

        OR

            on Error Goto ExceptionHandleLabel

            set Viewer = CreateObject("DExplore.AppObj.7")

        ExceptionHandleLabel:

            'HERE YOU CAN HANDLE THE EXCEPTION


    If a error ocurred in this moment, you don't have a help 2 installed,
but if any error ocorred, you can use the viewer

Re: check if MS Help 2 Runtime exists   

....otherwise H2 has 2 main COM dlls you can check
http://www.mshelpwiki.com/index.php?page=Help2API
If you can connect then H2 exists
But as Gustavo says Dexplore is a valid check as well (since DExplore akways 
accompanies H2 runtime files at the present time).
Cheers
Rob
