Adobe Acrobat DC Win 10 64bit download

Please read my previous response:

Currently there is no 64-bit version of Acrobat for Windows. 64-bit versus 32-bit would not account for the performance issues you are experiencing.

Adobe has not and will not significantly pre-announce new features, but you could reasonably assume that 64-bit version of Acrobat Pro DC (not Acrobat Pro 2020) is on the horizon. That having been said, 64-bit support allows for larger documents and operations thereupon, taking advantage of more virtual memory (and hence more physical memory). But in general 64-bit does not improve performance.
