I purchased two iMac's within the last month. The online up-to-date program allowed my wife's to go through, but not mine yet. Apparently this is a known issue. I've submitted the online request form to obtain a serial number by uploading a copy of my receipt. In the meantime, is it possible and/or legal to copy the image from my wife's computer and install it until I receive the code? Then when I receive the code, download the image for my own safe keeping on my app store account?
