The page linked in the README (http://osvr.github.io/using/) is still live but the links for Windows Runtime files or SDK are dead.
For example: http://access.osvr.com/binary/osvr-sdk-installer
I have seen in the past the page dev put it back on, and I'll try to ping the owner in Reddit but it would be good if there is any other live source for this.
Trying to compile (and update as needed) all the OSVR/HDK components and currently stuck with OSVR-RenderManager.
Thanks
