hello everybody

I have that error when i try to install service pack 1, I already tried with System Update Readiness Tools and doesn't work no way. I unchecked antivirus and firewall too.
I ve attached the checksur.log

Try doing a sfc /scannow action (open up an elevated command prompt and type sfc /scannow).
