How to upgrade Acrobat Reader DC.
The PC is a 64-bit machine and it is windows10.
I haven't applied the patch until now, but will all the patches up to now be applied by applying AcroRdrDCx64Upd2100120138.msp (21.001.20138 option update, February 15, 2021)?

No, not yet. That having been said, the only thing that the x64 versions of Reader and Acrobat Standard/Pro will get you is the ability to open very, very large PDF files and/or perform exceptionally complex operations on very many / large files.

There is absolutely no performance gain with x64, despite public misconceptions about same.

(Note that for Microsoft Office, the x64 versions primarily assist with exceptionally large and complex spreadsheets or with very large e-mail archives in Outlook!)
