Where can I find a download link/file for Quicken Deluxe 2016 for Windows?

I currently have this version running on my computer, but just bought a new computer and would like to get it installed there instead as my current computer is on its last leg. I have my original order confirmation PDF and it confirms that it was a download, not a CD. I don't see a downloaded file on my computer anywhere that I can find. I'm hoping there's a link somewhere that I can use for the download? Thank you!
