I've just installed V2016.1.1.5823 on OS X Yosemite, and when I launch Wwise, a Windows-style splash screen comes up wanting me to install MICROSOFT VISUAL C++ REDISTRIBUTABLE FOR VISUAL STUDIO 2013. When I agree and hit Install, it opens the folder "drive_c", and that's about it. I don't see a way to take things any further. The folder contains msvc2013.exe, and the folders Program Files, users, windows.
This is my first install I've tried using the new Launcher system.
