I know, I know - but I already contacted EWQL site with no help forthcoming. Finale tells me to "just add the PLAY_VST.dll to the Aria VST folder. I tried that. But I keep getting a note that says, "nothing registered to read files with extension dll."
Brief history: I did have EWQL SC loaded and working in Aria before windows 10 attacked. After removing windows ten and going back to windows 8.1 I reinstalled all of my music software. EWQL SC works fine as a stand alone, but I can ot get it into the instrument list along with Garritan instruments like before.
