Universal Control 1.7.4 (v5773) Release Notes
April 21, 2016
This update to Universal Control for PreSonus FireStudio Interfaces and Gen 1 StudioLive Mixers is to support co-install with the latest Public Beta version of UC Surface (v 1.5.1) on the same system. Also, this release removes the necessity for 16.4.2 Console mixers on firmware earlier than 1.13 to install and update firmware using UC 1.2 before updating to later versions of UC. Customers with 16.4.2 firmware earlier than 1.13 can now update directly to the latest firmware using this Public Beta release.
Improvements:
● Co-­Install compatibility with Public Beta Universal Control ­AI / UC Surface software. Both software control panels can coexist on the same system at the same time.
NOTE: Simultaneous operation of StudioLive­ AI mixers with FireStudio interfaces or 1st generation StudioLive mixers is not supported. This driver and control panel will not control the new StudioLive ­AI series mixers.

Crap, I wonder if that means it will not work at all or it means don't call us if you have any issues. LOL.
Thanks for the info though.
