Maybe your CD/DVD drive is a old drive :O( , for the new cd´s/DVD´s on the marked today actually many times you need a new drive for read them. Try first if you can install with the dll found on the link below.
You can find "wnaspi32.dll'' here : http://www.dll-files.com/dllindex/dll-files.shtml?wnaspi32
1: get a external drive(not to old) and try install it with that
2: copy the cd to a usb storage on a computer thats have a new cd/dvd drive, use the usb storage to install it on your computer, use the dll file from the link.
Hope this can resolve the problem.
