When running the installer for 2026.1 I get a message that the OS is not supported and some Connect features may not work.
Is Windows Server 2019 no longer supported? What Connect features “may not work”?
Connect is supporting each 64 Bit Windows Desktop or Server version which is in Microsoft’s mainstream support period, as per Microsoft Lifecycle Policy | Microsoft Learn.
Using any other not supported OS may work, but there’s no guarantee that there won’t be any problems.
