Some people have reported that when they attempt to update Eos Family Software on their console it appears to update but when it boots up the next time it still reports the same software version.  When this occurs the installer will run very quickly, almost as if it isn't attempting to install files.

Explanation of Issue

This issue seems to be caused by an issue in a registry file.  We have created an installer you can run to change this file and then be able to safely install the updated Eos software.


  1. To obtain the fix for the broken installer, please contact Technical Services.  We would be happy to send this to you via e-mail.  
  2. If you prefer, a re-imaging kit can be shipped instead.  This is a USB stick and some instructions which will completely wipe and restore the consoles hard drive.  To obtain this kit please contact Technical Services.  Have the serial number of your console ready and we can ship a kit free of charge.
