Hello mimilazarevic1992,
may you try it again?
after you reset the device, the upgrade notice should pop up again,
then you run the process again from there.
please do not install any other thing separately before this,
if there is any error message during the process, please kindly provide a screenshot.
If not, all the drivers and APPs you need for screenpad 2.0 would be installed itself.
I'm sorry that your device does not support Asus Control system interface v2,
so for your confusion about My ASUS, please refer to below link
[MyASUS for Windows] Why can I only see the Thank you.
