I recently upgraded to Acrobat Pro 2020 for Windows, TLP license. According to this, it is a 64 bit application, but after I install it, it is 32 bit. Can anyone clarify this? I am unable to find any more information about it.
Personally, I think the writer of that FAQ was mistaken/confused - "64 bit compliant" - it runs on 64-bit systems and installs 64-bit drivers as needed. But when Acrobat 2020 was released Acrobat ITSELF was a 32-bit application. I would expect this to be an upgrade to a future version (for example Acrobat 2023, if there ever is one).
Subscribers get continuous upgrades, so they did get the 2021 upgrade to 64-bit Acrobat app, at least in some countries.
