SureSync can synchronize data to operating systems such as Windows 2008, and non-Windows machines such as Mac and Linux via UNC path but the software itself must be installed on one of the supported operating systems.


SureSync can be run on Windows operating systems host in virtualization software such as VMWare of Hyper-V without issue. Each virtual machine involved in the synchronization / replication requires appropriate licensing.

SureSync Database Requirements

SureSync requires a SQL database to store configuration information. The following versions are supported:

  • SQL Express 2012 / SQL Express 2014 / SQL Express 2016 / SQL Express 2017 / SQL Express 2019 / SQL Express 2022
  • SQL Server 2012 / SQL Server 2014 / SQL Server 2016 / SQL Server 2017 / SQL Server 2019 / SQL Server 2022

Required Microsoft Components

SureSync requires a number of Microsoft components to be installed. The SureSync installer will detect the versions your system is running and offer to upgrade them as needed.

  • Microsoft .NET Framework 4.8
  • Microsoft Visual C++ Runtime 14.0 Update 3

Please note that using the SureSync installer to install these prerequisites could result in a reboot being necessary before the setup can continue. If a reboot is necessary, the installer will prompt you. In environments where a reboot is disruptive, we recommend installing the required components manually during your normal maintenance schedules and then proceeding to install SureSync.

Consider installing the required components with Windows Update or a third-party patch management tool if you use one. This ensures that all machines have the necessary components before you start installing SureSync.
