Spore will not Install

[fanceefish]

Hi- I have a problem.
My son bought Spore and was able to install and play it at his grandparents house. He brings it home and nothing.
We insert the cd and nothing.  It says 'insert disc' -however the disc is inserted.  We have windows xp- we have no problems running anything else or installing other games discs and so forth.
What should I be doing? What can I check? Please help me.
Thank you!

Can you make sure if it works on another computer besides at his grandparent's house.

Are there any scratches on the disk?

Also, on your computer, Download, and install Everest: http://www.majorgeeks.com/download4181.html
Open it, click Computer, then Summary.
In upper menu, go Report>Quick Report-Summary
Save it in text file, and paste it in your next post.
Don't include anything under line Debug - PCI
