The HARK software installation instructions can be found in HARK’S website. (https://www.hark.jp/) The installers for Windows can be downloaded directly from the website. For Ubuntu, follow the instructions in the website on how to register the package’s repository, and how to proceed with the installation. HARK’s source code can also be downloaded as long as the repositories are registered.
For first-time users, it is strongly recommended to use the Windows package. The installation from source code on the other hand, which is for advanced users, will not be covered in this document.
