Troubleshooting:changing serial port numbers

changing serial port numbers

I have installed a ftdi usb->serial device on my win8 machine.
All the drivers, etc., seem to have loaded OK and device manager says the device is working.
My problem is that the 4 serial ports are installed as COM11-14.
The software I use does not support
COM port numbers that high.
I tried to change them in the advanced section of the device manager, but win8 tells me that I must have "write privileges  in the registry..."to make the changes.
I have Administrator privileges; what more do I need to do?

Thanks - John
