Windows 10 AIEP3 and others fail while installing with a c++ redistributable error

All of my Air products (AIEP3, Loom II, Creative FX Suite, etc.) were working a week ago.
Then, for various reasons I did a clean re-install of Windows 10 (Home, 64-bit, i7 processor, 32GB of RAM, much HD space), and have been unable to install any of the plugins.
They all authorized properly with iLok, but during installation, they will get about 2/3 of the way through, and fail with an error related to a Visual C++ library. (see image for a typical example)
