Solution 1, under normal circumstances you can use this solution to solve the issue.

Solution 2, If no "VCom" device is shown and it is already listed as "Neets control systems VCOM driver" under Ports (COM & LPT) you can use this solution.

Solution 3, If you have a Windows user account without Administrator rights, see Solution 3 at the bottom of the article on how to install the drivers. 

Solution 1, Installing VCom Driver

Go to Windows Device Manager and look for a 'VCom' device that is not installed correctly:


Then right-click on the 'VCom' device, and select "Update driver"


Select "Search automatically for drivers"


Driver is now installed and it should get detected by Project Designer immediately.


Solution 2, Reinstall the driver

If the above didn't help or you already have the drivers installed and you still have no contact to the control system, go into device manager and delete all of the ports in the Ports (COM LPT) section.
Then, disconnect and reconnect the control system and wait for the driver to automatically install.


Solution 3, Installing drivers without administrative rights

Open Device Manager by clicking WIN and typing “device” and press ENTER.
