Downloading Acrobat Pro DC 2015 12.0 MLP?

I purchased a copy of "Acrobat Professional DC2015 12.0 MLP AOO License UE (65258634)" on 2/3/2017. I have a new laptop, and I'm trying to download this software again. I can't figure out where on Adobe's website to do this. I can easily find the option to download a free trial of the subscription based Adobe Acrobat Pro DC, but that's not what I have purchased. Any advice
