[Antennaware] HFSS

I'm trying to reconcile

   http://oem-shop.us/cheap_download_Ansoft_HFSS_9.1_(1_cd).html

and

   http://www.gohoy.com/html/Finite%20Element%20Analysis%20engineering/20080415/11373.html

after a minor Google search on Ansoft HFSS

Is oem-shop an Asian Rim knockoff clearing house?
