Same problem here.
It started the 24th, problem is that I installed w11 during that time, too.
So, I thought it was w11 related, went back to w10, returned to w11 again, but the problems with AI Suite 3 and Armoury Crate not detecting the motherboard remained, no matter what.
I´ve been trying since then (the 24th) to solve things, uninstall, reinstall the Asus apps, searching the internet for solutions, so much time, the whole weekend wacked, til I found this thread...
I´ve been a satisfied Kaspersky user since 2010 and have always bought a 5-pc activation, without any big issues...til now.
Please solve this or I´ve to uninstall Kaspersky for the first time in more than 10 years!
