home office 2007 not trial won't accept product key

[Danthe4th]

My daughter is desperately trying to finish her homework and for some reason the home and office word 2007 has suddenly decided to stop working.
This was bought by me and I have the disc with the product key, its still working on my laptop, its not a trial version.
Any ideas anyone??

It just keeps asking for the product key but says its invalid.

Not happy as my other daughters dell laptop has just died and its got a brand new hard drive which I wasted £100 on, anyone want it??

anyone???

"its still working on my laptop"

So you've got it installed on both your machine and your daughters?

If so that's why it's not working, a copy of Office is "a" copy of Office and is meant to be installed on one machine.

Your daughter could download some free Office Software (Open Office is really pretty good) or you'll have to buy another copy of Office.
