greyed serial port

Sorry for the newbie question, and i looked on the forums before posting this but nothing seamed to help

Im using windows 7 tryed to do the drivers update thought it worked, but i saw somewhere someone said to try uninstall and reinstall it, that didnt work, and im kinda out of ideas so could someone please help

Are you saying from the Arduino IDE menu, when you select Tools, Serial Port, all the choices are grayed out?

For windows 7, 64 bit, download and install

I had windows 7, 64 bit, so I'm not sure if this applies to the 32 bit version. I recall installing the drivers under windows XP and mac OS X too.
