RE: error code 3!
If you are logged in as yourself, make sure you have WinSCP configured to switch to sudo. This will give you the permissions you need to do everything.
try this in the connection configuration:
On your first screen, switch your File Protocol to SCP
Then on the SCP/Shell screen on the Shell Input field type /bin/bash -c 'sudo su -'.
