I got a laptop that came with the OEM Cyberlink blu-ray software (Power Director). However, I did not get a hard copy of the software. I upgraded my laptop from Vista 64 to Win7 Pro and I want to be able to use my BD-ROM but I do not want to buy another blu-ray program. I still have an image of the old Vista in my WHS box. Where will I go to extract the key so I can download the Power Director and install it?
