The following versions of EwE are available for download (see the EwE change log):

This release contains bug fixes to EwE 6.6.1. Yes, release 6.6.2 is skipped here. Most notable features:

  • Ecopath model from Ecosim now reports proper diets
  • EwE Pro license logic has been internally standardized

Note that EwE is no longer compatible with Windows XP. EwE may work on Windows Vista, and has been tested on Windows 7 and newer.

This version of Windows relies on .NET framework 4.5 or newer, and requires Microsoft Access drivers to read and write model files. Note that the 32-bit version of EwE only runs with 32-bit Access and/or Office drivers; the 64-bit version of EwE requires 64-bit Access and/or Office drivers.

@SysAdmins: to install EwE silently, run the installer package with parameters /SILENT /VERYSILENT

This release mostly contains bug fixes and usability updates to EwE 6.6. Most notable features:

  • Ecospace scenarios can now be created and deleted under all circumstances
  • Drawing errors such as in the MTI plot have been fixed
  • Ecopath models from Ecosim are now generated over an entire Ecosim year in accordance with the basic Ecopath assumptions

Note that EwE is no longer compatible with Windows XP. EwE may work on Windows Vista, and has been tested on Windows 7 and newer.

Additional downloads

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This version will complain that it is outdated on launch.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

EwE 6.6 requires Windows 7 or newer, .NET Framework 4.5, Microsoft Access 2007 or newer, or Access database components 2016 or newer. Due to technology creep on Microsoft’s behalf, we can no longer ensure that EwE software runs well on Windows Vista or older.

EwE 6.5 and older 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.

Should I install EwE 32-bit or EwE 64-bit?

EwE 6.6 still relies on Microsoft Access drivers. In order for this to work, EwE needs to be of the same ‘bitness’ as your local office installation: if you run 32-bit Office /Access, EwE MUST be 32-bit too. If you run 64-bit Office/Access, EwE MUST be 64-bit too. Most organizations run Office in 32-bit. You can find plenty of resources (such as this one) on the web that help you identify the bitness version of your Office installation.

In general, Ecospace scenarios run with more ease in 64-bit.

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.
