Hi,
I've issues too with Aura Crator version 1.2.4 with Armoury Crate version 2.6.4.0 in Windws 10 in Spansh; only a few effects worked in white color or default rainbow, but most didn't. As suggested here, I've switched the display language for Windows 10 to English (USA) and now Aura Creator works fine for me, no reinstallation needed.
Now I know for sure that it's an Aura Creator malfunctiont, not my HW or SW evironment. But, come on! I'ts not reasonable to chage the entire system laguage to light up some LEDs.
Please Asus, fix this, if it works in English should work in other languages.
Thank you so much for the advice!
