Plug in Topaz 4 query

[caspia1]

I have a Topaz Remask 4 plug-in.
How do I save it in PSP x6 (64bit)?
I go to Preferences - file locations. The plug-in is there. There are a number of file types on the left hand side (from brushes all the way through to workspace). Which one do I select to add it to and how do I open it once this is done? I want to save Topaz Remask image editing as pspimages.
Please advise.
Thanks.
