Is there a more detailed description of how to get this to run? I cloned your repo and followed [Installing on Windows](https://google.github.io/mediapipe/getting_started/install.html#installing-on-windows)

On Step 9 the bazel build throws some errors: "GET returned 404 Not Found" So the files are not online anymore. I wonder if i am following the right path anyway.

Thanks in advance for any hints :)

Can you please try [#70](https://github.com/google/mediapipe/issues/70) and [#5013](https://github.com/bazelbuild/bazel/issues/5013) and let me know if this fixes your issue?

Also, make sure the ENV variables are correctly pointing to the locations.
