Hi,
Thanks for the info.
Since posting have you rebooted the notebook? I ask as the last thing mentioned in the installer log is that a reboot is required.
If that doesn't help, please run through these steps to help diagnose the issue:
1. Disconnect the adapter
2. Uninstall the DisplayLink software
3. Download and run the Cleaner tool from here:

4. Install 7.4 M0 from here:

5. Reconnect the adapter
Thanks,
James
