Had the same issue, reinstalled the Nvidia driver, Direct X 12, several other graphics settings, all to no avail.
Then had the genius idea that Wwise's wireframes couldn't possibly be harder to render than any retail game, so I figured their installers must be of some help.
Solution:
1) Download Steam
2) Download basically any half-decent game with 3D support
Steam will be smart enough to realise you don't have the right C++ redistributables, know which ones to install and where (it's a nightmare to install the correct one manually to fix this issue, so don't even try), and next time you open Wwise (might need a PC restart) the 3D object viewer will work. (If this solution didn't work, your game wasn't decent enough.)
