Moving NIS Windows XP to a new computer with Win 7

Pretty much a newbie here.... and I've looked through the messages and can't find anything to answer my question. I just got a new PC with Windows 7 and I have almost 300 days left on my 2009 NIS subscription, but it's for XP. Is it possible to get this transered into my new PC? I hate losing all the time that's left on my subscription but I can't figure out how to do it.And of course it won't let me install from the original disc and then run Live Update.

 

Can any one help?

 

Thanks
