Ecopath 5.1 (2005)

This is the last version of Ecopath 5, prior to the overhaul to .NET and the subsequent releases of EwE 6. Ecopath 5 contains a few features that were not migrated to EwE 6 for various reasons; you might want to use this version if you need access to legacy features such as EcoRanger and the auto mass-balance routine. It is recommended to install Ecopath 5 on Windows XP. You might need to install a virtual PC environment.

This version will complain that it is outdated on launch. Just enter ‘Polovina’ in the panic box and Ecopath 5 will start.

Please note that we are no longer making changes to the Ecopath 5 source code; Ecopath version 5 is no longer being maintained.

Installation notes

All EwE 6 versions require Windows XP SP 3 or newer, .NET Full Framework 4.0 (not .NET Client Framework), Microsoft Access 2007 or 2010, or Access database components 2007 or 2010.

Note for users of Windows 8 or newer

If you receive a Windows Smart Screen notification while trying to install or execute EwE such as

Windows protected your PC
Windows SmartScreen prevented an unrecognized app from starting, Running this app might put your PC at risk.

then simply click the “More info” link under the warning, and click “Run Anyway”. Anti-virus solutions such as Microsoft SmartScreen and Avast will start trusting software the more it gets installed.
