I downloaded and installed the ARIA update 1.6.2. In the Program Files folder--folder Garritan/ARIA Player, the file ARIA Player x64.exe shows date 12/13/2012 and version 1.6.2. However, in the folder Garritan/ARIA Player/VST, the ARIA Player Multi VST dll files show the date 4/29/2011 and the version 126.96.36.199.
Over in the folder Plogue/Aria, the file aria_x64.dll shows the date 12/12/2012 and the version number 188.8.131.52.
Then in the Cakewalk/Vstplugins/Garritan folder, I once again see the files version 184.108.40.206.
This seems to me like something went wrong in the installation. Should I simply copy the dll files from the Plogue folder and delete the versions 220.127.116.11?
UPDATE: Never mind. I tested Sonar and I tested Finale, and ARIA shows version 18.104.22.168. I'm guessing that the VST folders are pointing to the Plogue folder to get the engine.
