Continual Activation of XP

Try this...boot into safe mode command prompt. browse to the system32 folder under the Windows folder. Look for a file called WPA.DLL. copy it to a disk, thumbdrive, etc.. and then rename the version on the PC to something like WPA.BAD. Restart. You should be able to go through the activation process one last time. Cross your fingers and restart again. Hopefully this will solve your problem.
Obviously, if your PC won't boot into windows after renaming that file, put it back the way it was by changing the name back to WPA.DLL

He means wpa.dbl....

There is no wpa.dll.

Also, unfortunately, that 64 million digit key code you entered will not work again.

In fact, this process will not work, sad to say, though it sounds logical.

The problem is not in the wpa.dbl file, which includes your activation info, but somewhere else.

If you want, there is another process (well, two, really) that may work, but given this is a relatively new machine, you will be far better off with a fresh install, or repair.

Either way, you are going to end up calling Microsoft for a new passcode.

So, anyway, if you want to try, try this:

Start > Run, type
regsvr32 regwizc.dll

Then, START > RUN type
regsvr32 licdll.dll

Reboot. Windows should ask you to reactive. As noted, though, if this fails you will be making yet another call to Microsoft.

the other solution involves a minor registry edit, but I doubt that will work either.
