Can't install Viper4Android

Hi, I have a problem with Viper4Android. It doesn't want to to install.
What i've done/tried:

- Phone is rooted
- Running CM13
- ElementalX
- SELinux set to Permissive on every boot (SuperSU)
- Tried installing driver through app and zip (flash)
- I have deleted /system/vendor/etc/audio_settings.conf

What should I do/What did I do wrong?
