How to get Dopus to use my Vista preview handlers?

I was able to preview zip files and a bunch of other file types in Windows Explorer's preview pane (Vista Ultimate 32-bit) thanks to the MSDN Preview Pack.
But I can't figure out how to make Dopus use these handlers for its preview pane, although I'm sure there's a way to do it, given how flexible this program is.

Any help would be dearly appreciated as usual - thanks in advance!!

You may be able to use them via the ActiveX + Preview + Office + Web plugin.

See if they appear in the plugin's configuration window under Settings -> Preferences -> Plugins -> Viewers.
