For downloading the client we recommend different methods for Linux and Windows server.
Though you could use same method for both OS it is more convenient to use the method that does not require additional installations.
Windows Server (curl)
As from Windows server 2019 the CURL software is preinstalled with the OS, thus we recommend using it to fetch client package:
curl _url_of_package_from_servers_detail_page_
This will save the package to current directory under the name arkusto.zip.
Linux server (wget)
Most linux distros come with bundled wget utility for downloading files.
wget -O newname.zip _url_of_package_from_servers_detail_page_
This will save the package to current directory under the name arkusto.zip.
