A setup problem is preventing the driver to be installed properly. This happens after installing version 7.00 on a PC where version 6.51 is already installed. To fix this, the user needs to reinstall the cd_protdrv setup manually after a restart of the system, by executing the setup from the Additional_Software\COPA-DATA Multiple Network Protocol Driver x86 / Additional_Software\COPA-DATA Multiple Network Protocol Driver x64 folder.
