 - Windows Server 2012 R2 
 - Windows Server 2016

SmartZone runs in 64-bit, 32-bit, and AnyCPU-compiled executables on Windows. Although it may run, SmartZone is not supported on earlier operating system versions, such as, Windows 7.

- Ubuntu 20.04 
 - Ubuntu 18.04

On the RedHat 8 operating system, SmartZone License Manager may not work since some cryptographic protocols are disabled by default. In this case, to install a license on the local computer, required mode can be enabled with the following command (run it as a root):
update-crypto-policies --set LEGACY
After installing the license, default mode can be enabled with the command:
update-crypto-policies --set DEFAULT
