When starting the Upgrade Tool USB-CAN Dongle the error message ILLHW appears.

The latest Windows operating systems (´WINDOWS Vista, 7, 8) do not support the standard USB CAN-Dongle DLL file. If the error message ILLHW (illegal hardware) appears, then, after installation, replace the file "PCAN_USB.dll" in the install folder "C:\Programs\Drive Download Utility–USB\" with the separate file "PCAN_USB.dll" from the downloaded PCAN_USB.zip archive using the Downloads tool.
