I just formatted a pc and trying to install XP Professional SP1 on it. I enter the product key thats listed on the pc and it works all fine and dandy until you reach the welcome screen for the first time. It says I must activate before I am allowed to login... ok so I choose activate, online activation does not work so I choose activate by telephone. Its supposed to list an installation ID to give to Microsoft, but its just blank. MS support hasn't been any help. I've googled it and found that one solution is to install the network drivers in safe mode. I was able to install the wireless drivers, but the LAN drivers would not cooperate. Still no luck. Please help. Yes it is a genuine copy.
