Hi Duncan, jup, working locally here. Is the Windows 7 you are using 32 or 64 bit? (just curious) The driver versions etc are the same. I am using the same installer files as I was using before on numerous others where I did not run into any issues. The only difference between the machines is the Screensize (Lenovo L430 and L530) RAM, CPU etc are the same. EDIT: I just "restored" the Windows to a state before all that and installed again using brand new files freshly downloaded. Now I get a Bluescreen everytime the dongle is connected.
