Get Genuine Online Kit; 32 => 64 bit (Windows 7)

Regardless of whether they are full install DVDs or not they should show up in windows explorer. There has to be files on them for them to do anything. Your optical drive is a DVD drive correct? Windows 7 install media is a DVD not a CD. Do other disks work OK in that optical drive? Have you tried those disk's in another PC to see what happens?

Take look at the email from your Retailer, you will find a link to 32bit ISO & 64bit ISO.

No clues in the email from the Retailer by the way. Here I could only find a reference to the key activation. This works OK, but does not take me any further in using the (64 bit) installation CD.

Relook at your email.
