Hi MDamerco and Sheepforwheat,
If you haven't done so already, please just delete the currently installed EUU that you have. For Windows: my computer>C drive>Program Files>Eventide. Here you will find the "update utility" folder, and delete it.
For Mac: Find Eventide Update Utility in your applications folder and trash it.
Then visit the Timefactor Support page and reinstall the EUU. Reattempt to install the OS. If the unit is currently on version 1.1 or earlier, it is then necessary to hold down the middlefootswitch to place the unit into "update" mode.
If attempting to update the OS again you find the issue remains, please confirm and I will open tickets for you and assist you both directly offline.
