Updated AI Suite III V10054 fixed this error. I'm not sure why, but Asus hasn't posted this AI Suite III update on the Z-87 Pro's download page. Raja posted this over at the ROG forum: https://drive.google.com/folderview?...k0&usp=sharing
One problem with AI Suite III has been solved for me (yay), yet new problems with the software have came up that were not there before (booo). I give up.
