If you are currently using an English-based version of Acrobat on Windows and are willing to do a bit extra work, you can access the new 64-bit version of Acrobat at https://helpx.adobe.com/acrobat/kb/download-64-bit-installer.html.
Two warnings, though!
(1) At this point, that is not an updater installer. Thus you must totally uninstall Acrobat and then install using the new installer. Note that this will not preserve many of your preferences. Be prepared for a bit of time and effort to customize back to the way you prefer Acrobat to operate. Eventually we will have an installer that is also an updater (that works).
(2) More important, if you are currently using any third party plug-ins to Acrobat on Windows, until those plug-in developers provide 64-bit versions of their plug-ins, don't migrate to 64-bit Acrobat.
Good luck!
PS: I am successfully using the 64-bit version on all my Windows 10 systems.
