Support for Operating Systems and Versions not Identified Above

Support is provided for the OS and versions listed above. Unless explicitly identified as a supported version in the Requirements for Each Managed Machine section above. This includes, but is not limited to, newer OS versions that have not been explicitly identified.

Any device running an operating system not listed above, or with a version older than the stated minimum, is unsupported. Although it may be possible to install the agent and some functionality may operate, please be aware that:

  • Kaseya does not test existing or new functionality on unsupported device types and cannot guarantee that functionality or connectivity to the platform will be maintained when releasing new product versions or updating infrastructure.
  • Kaseya may, at its discretion, explicitly block devices with unsupported and end-of-life operating systems from connecting to the platform without prior notification if required for platform security or regulatory compliance purposes.
