**Important note**: if you want to transfer the installed Inference Engine binaries to another machine w/o running OpenVINO installer there, you need [the redistributable files of Intel C++ compiler](https://software.intel.com/en-us/articles/intel-compilers-redistributable-libraries-by-version) (use the latest update, 64-bit version), otherwise the Inference Engine or some of its essential plugins will refuse to load and run, which may result in an app crash.
