Adobe Acrobat Reader DC MUI

Good afternoon,
after a long period using only the 32bit version of Adobe Reader DC MUI, I'm considering to install the 64bit version on 64bit operating systems.
To do some tests, I've downloaded both versions (32 and 64bit) of the same software from here (Adobe - Adobe Acrobat Reader DC Distribution) selecting the OS version, language (MUI) and dowloading the files.

Sorry for aking but why the two applications have different names?

32bit:

64bit:

Even the links on the desktops seem to refer to different software and this could create confusion among users.

Thanks.
