To run Chirok in Windows you may need to install the MS Visual C++ Redistributable for Visual Studio 2017.

The Linux version of Chirok is compiled in Ubuntu 20.04 LTS, thus it should work in any rather new distributions. It will probably not work in CentOS or similar “conservative” distributions.

The MacOS version of Chirok is compiled in the latest MacOS X 10.15.4.
