Installing original UT2k3
 

Hi all, after a few days that i have borrowed a friends copy of the above game , i have decided to buy it, will get it tomorrow, but i was wondering , having still got the game in my PC plus all the patches and maps, can i just change CD key with the one i am buying ,in order to play online, or do i need a fresh installation?

Thanks for the help

Just reinstall the game. There might be a keychanger out there but by the time that you found it and used it, you could just as easy have reinstalled it.
