After two days of a try and error process I have found a solution and a new problem.
Using a USB Port that does not work before, I have tried a different combination of connections of my mouse, keyboard, etc.
Then, install the drivers and choosing repair.
My VC now opens, try to sync the Virus but, 2 or 3 seconds later, it lost the USB Connection ("A communication error has ocurred. The device does not respond to request messages or the transmited data is corrupt")
Vista x32, Ableton Live 7, 8 Gb RAM (4)...
Keep trying
