Error conflict communication port

Specs: Windows XP
Help me please.
My PC is connected to a Olivetti printer through COMM1 port and I installed driver for the printer, but after do this, i can not program to open comm port in C#. The Error display: The given port name does not start with COM/com or does not resolve to a valid serial port

(I use device manager to uninstall driver and can open COMM port, but when i restart windows OS, my PC still is conflicted as at first).
I want to write a program, which can uninstall driver in device manager automatic when windows os is started, Instead of using manual divice manager of windows

All the best
