Cant install any driver

[Carlos]

Hi, I am trying to get a Kensington sd3600 dock to work and I cannot install a DL driver. It keeps telling me "the software package appears to have been modified". I have tried downloading v8.0 and v7.9 from different sites, it keeps aborting the installation with the same message every time.
I was using another dock, and before installing the new one I unistalled a previous DL driver. I run the DL cleaner. I also run the DL support tool and attach the report, in case that might help.
