EEE Software Requirements

EEE leverages the Microsoft .Net framework, SQL Server and SQL Server Reporting Services software components and as such, specific versions of EEE have explicit dependencies on a certain versions these components.

While there is no explicit block or requirement on operating system enforced by EEE, this may be limited by the version of the software components (e.g. .Net framework) available for your Operating System. We recommend running current, regularly updated and supported operating systems.

See here for more information about the .Net framework requirements.
