"Kensinton Display Adapter is not supported on this operating system version"

Can you tell me what version you are trying to install from the dock? You should be able to install the Kensington v5.2 or v5.5 from the Kensington website for this dock. Then you can upgrade to v6.1 from the DisplayLink website. But you do need to have v5.2 or v5.5 from Kensington installed first, otherwise the dock will not work properly. Thanks Wim

The software from the device that usually installs automatically when you connect the usb cable does not even connect. So the 6.1 software that i downloaded from the support page was the only version I installed. do you have a link to the v5.2 or v5.5? I will try installing that first. Thanks M

The v5.5 software you need is on the Kensington website here: Wim

Software for Display Adapter not supported 

Uninstall all DisplayLink software, then install v5.5 from teh Kensington website. Once that is done, you should be able to upgrade to v6.3. If you installed 6.3 and then v5.5, V5.5 would not have been installed properly as the installer would have seen 6.3 as a newer version. Wim

still not working with Windows 7 (64-bit)
