Microsoft Windows defender

[Guest]

While Installing Windows Defender we are getting following error. for your
information we are using licence cd for xp the error is " The computer has an
invalid Volume License Product Key(VLK).To obtain a valid key,Please contact
the computer manufacturer or the company from which you purchase the
computer".
We have tried on more then one PC's all are installed with valid License for
XP.
Please send the solution for this problem.

This error isn't related to Windows Defender, per se, but to Windows Genuine
Advantage, which is a prerequisite for Windows Defender.

There's lots of information about WGA here:

You can open a free email support incident with the WGA folks, via this
link, I believe:

Since this aspect of Microsoft's anti-piracy efforts is of great interest to
many here, I'd be very please if you can find the time to let us know how
this works out?
