Windows 7 and Windows Server 2008 reached the ends of their lives in January 2020. The operating systems are no longer supported by Microsoft or Burli.
While we don’t expect Burli to stop working on Windows 7 right away, based on past experience, the latest versions of Burli will probably start to fail on Windows 7 at some point as core modules and technologies inside Windows evolve.
In other words, versions of Burli relesase after sometimes in mid-2020 may not work properly (or perhaps at all) on Windows 7.
The good news is that Burli works very well (no known issues) with all of the more recent Windows operating systems, including Windows 10, Windows 8.x, Server 2012 R2, Server 2016, and Server 2019.
Windows 10 (up to and including version 1903) and Server 2016 are now widely deployed, stable, and we actively recommend them. Windows 8.x (which almost no one uses) and Server 2012 R2 work well with Burli, but will reach their own end-of-life in 2022 so are probably not useful as upgrades for anyone not already using them.
Also note that support for Microsoft’s SQL Server 2008 database ended in early July 2019.
