I have a computer that I want to put a WPC54G into. When I try to install the software, I get the message "The WLAN monitor utility and drivers for the WPC54G have already been installed. Wireless-G Notebook Adapter" When I go into the Control Panel, Add /Remove Programs, it is NOT there. It is not listed in Start, All Programs. Can anyone tell me what I need to remove so that I can reinstall it.
