Unlocking K810i under windows 7

Hello
I have a problem unlocking UK based SE k810i. I downloaded XS++ v3.1 and setool2 lite. First thing i wanted to do is to identify my phone, but nothing.
This is what i get. Same story is with setool. Is it because i use windows 7? I tried to update USB drivers, windows has done it already and i cant upgrade it.
