Driver install not working on Yoga 2 Pro with Windows 8.1 Professional

[olabil]

Hello,
I have gone through the steps. There are displaylink drivers installed, but does not look as in the instructions. Also, the actual software is not installed at all.

I have also attached the output from the support tool.

The main problem for me, as it seems, is that the software does not install. I am not prompted at all after I have authorized the program to "make changes on my computer". Just a very fast flash and then it stops.

Any clues would be highly appreciated.

Thanks,
Ola
