Short report and possible advice for others who have got in to same trouble:
- Dock powered off
- Attempted to uninstall all packages related to D5000. Two failed to uninstall.
- Performed cleanup with tool supplied.
- Did manual cleanup from registry, reboot.
- Confirmed that all related entries, processes disappeared.
- Installed first Core package from Displaylink http://www.displaylink.com/support/downloads.php
- Installed additional package from Dell http://www.dell.com/support/drivers/...driverId=V6DXH
- Reboot.
- After connecting to dock, went through DisplayLink wizard configuring main and secondary monitors.
Results: success
The only comment i have is that secondary monitor (through D5000) now named in my devices as "No Monitor". I would say that does not hurt but better to name it in a different way
P.S. that also solved issue with Displaylink Audio device..
Thanks for your help, guys!
