Finding serial numbers

Hello,
I have just purchased a new laptop, and I am trying to put Hitfilm Ultimate on it. I originally bought standard, and then upgraded via a download. The serial number for that download is partially illegible, and as a result, I need to find it agian. I still have it on the old computer, so would there be any way to go back in and find the serial number? Please let me know if you have any sugestions.
Thanks a ton!
