QC as interface in Wndows

Hi! first of all, sorry about my poor English.
I cant use mi qc as interface on Windows.
I did install the drivers, put NueralDsp audio device, outputs 1/2 on the QC screen.
Works fine for listen music in all my sistem, but when i try to record guitars, the Daw only recibes a “clean signal guitar” , like isnt processing any sound of the qc.

USB outputs 1-2 is always the clean unprocess signal. The processed signal is found at USB output 3-4 (in 1.03 in multi-out or if USB 3-4 is selected)
