Element Eos Software Info

This article lists when every version of Eos Family Software was released. It also includes links to download each version as well as its release note. 


The Element information below highlights the software and hardware changes that occurred at each of the recommended Eos versions.

You can click the release date to download that version's release note.

The most recent release can always be found on the Eos Family product page at as well.


  • All Windows 7 Upgrades will be sent out with the most recent software version unless requested otherwise.
  • Version 3.0+ will only work on 64-bit motherboards (AAEON, Win7) and are not compatible with 32-bit (BCM, Intel) motherboards.  See the article here for more information on how to tell the difference.
  • It is not recommended to downgrade console software via the settings menu as it could cause unknown glitches that haven't been tested for.  Upgrades are only meant for upgrading.  It is always recommended that a console be re-imaged rather than downgrade if absolutely necessary (although upgrading is always prefered).
