"In 2011, during my school years, I purchased PS CS5 Extended for my MacBook. Recently, I acquired a new Windows laptop which doesn't have a DVD player. I've been attempting to download the app from your website, but I have a few concerns. I no longer have the student serial number as I'm no longer a student. Additionally, my new laptop runs on Windows, not Mac. Is it possible for me to use this app, which I purchased over a decade ago, on my new laptop?"
