You may very well be right. But it does not exist as part of the 2.7 GB upgrade install file that was downloaded from Steinberg. Nor, is it anywhere to be found once installed.
I did a complete uninstall of Cubase and eLicencer, removing all remnants of Cubase in Windows and the Registry and then re-downloaded and re-installed and same thing. No Acoustic Agent.
My email dialog with support has gone quiet so far today. I wish I would get some response. Even to acknowledge it is actually a problem.
