Because of some fine print?
Or because Microsoft's XP authentication system knows when you're
using an OEM product key incorrectly?
The OP should simply download several new versions of the XP cd via
torrent and try his key to see if it works on any of them.
Or, you can copy the contents of your XP cd to the hard drive and
install it from the hard drive, but first you need to modify this
file:
setupp.ini
Read the following:

====================
The Pid value is what we're interested in. What's there now looks
like a standard default. There are special numbers that determine
if it's a retail, oem, or volume license edition. First,
we break down that number into two parts. The first five digits
determines how the CD will behave, ie is it a retail cd that lets
you clean install or upgrade, or an oem cd that only lets you
perform a clean install?
The last three digits determines what CD key it will accept. You
are able to mix and match these values. For example you could make
a WinXP cd that acted like a retail cd, yet accepted OEM keys.
Now, for the actual values. Remember the first and last values are
interchangable, but usually you'd keep them as a pair:
Retail = 51882 335
Volume License = 51883 270
OEM = 82503 OEM
So if you wanted a retail CD that took retail keys, the last line of
your setupp.ini file would read:
Pid=51882335
And if you wanted a retail CD that took OEM keys, you'd use:
Pid=51882OEM
======================
Here's more examples of Pid numbers. These are taken from the
"System Builder" version of XP-pro (specifically the "2002"
version). The System Builder CD is what small or medium-sized PC
builders use when assembing systems from scratch.
This is from an XP-Pro SP1 CD with files dates March 31, 2003:
[Pid]
ExtraData = 786F687170637175716954806365EF
Pid=55274OEM
This is the same product, except with SP2. These numbers are the
same even for different file or release dates (and even for the
last version which included SP3):
- Aug 4, 2004 (sp2)
- Feb 28, 2006 (sp2)
- April 14, 2008 (sp3)
[Pid]
ExtraData = 786F687170637175716954806365EF
Pid=76487OEM
