It's 2020. We still do not have Acrobat Pro x64. Our company develops engineering solutions around the world for aerospace and car companies, and the aerospace models are enormously complex--despite all efforts to compress models and use other formats to reduce size, the fact is that Acrobat does not handle these well, often freezing or crashing (even more prevalent since the Windows 10 required switch, as Win10 is so consistently buggy). It's 2020 and there is no excuse that we're still asking for a 64-bit version of Acrobat Pro on Windows. If you've already moved to x64 for Mac, you've fought half the battle already. Please, get this done this year.
