Is there a merge module for HHActiveX.dll

I told the developer who creates our install images that we needed to install and register HHActiveX.dll because we are using the glossary in our RoboHTML help project. He asked if there was a merge module available for this dll which will allow us to be "well behaved windows developers" by allowing us to remove it when we uninstall without affecting other applications that have installed and registered it. He said that it should be created by Adobe and is a .msm file that effectively gives the dll a generic install ID so that the system knows that it is used by multiple programs. I've looked around the Adobe support site and through the knowledge base and have not found anything listed. Does anyone know if this is available?
