Is there a Windows 8 version of the hhactiveX.dll?

Maybe I should add some more information what this is about. This is the old issue with browse sequences, they only display on other computers when you register the hhactivex.dll provided with Robohelp. There also is a 64 bit version, but this evidently does not work with Win8 64bit. To make tthings worse, registering it on a Win8 64bit machine breaks the help viewer resulting in the chm not displaying at all.
