Is there anywhere that I can download a 64 bit version of Premiere Pro 2018?

I updated my mac recently to 12.0.1, and now my computer doesn't support 32 bit programs. I don't want to update to the latest premiere pro software as the 2018 version is the one that I am comfortable the most with. Is there anywere I can download a 64 bit version of it? Does it exist?
