Texniccenter Finnish Spelling, how to use Voikko with Texniccenter

I am using Texniccenter for writing LaTeX documents. Unfortunately, when I am writing in Finnish as I usually do, there is no spell checker in Finnish in Texniccenter. All the lines are underlined in red, and this is not nice. I know that there is Voikko for Finnish spell checking in LibreOffice, but is it possible to apply Voikko for Texniccenter? Texniccenter is using Hunspell; I downloaded the voikko-laaja.oxt file but I could not find in this package any files with aff and dic suffices.

Your Sincerely
