What operating systems are supported by Intelli-Site 4?

As of January 14, 2020, Microsoft Windows 7 and Windows Server 2008 R2 have reached end-of-life. Microsoft no longer supports these OSes. As such, OSSI no longer supports these operating systems. While our software will continue to install and upgrade on Windows 7 and Windows Server 2008 R2, we will not provide technical support for these systems for versions beyond 4.0.45.12.  All customers and integrators are strongly encouraged to migrate to Windows 10 or Windows 2016.
