Adobe Reader DC x64 base installer for slipstream?

Hello all,
I'm a little confused.
For some time now, the 64-bit version of Adobe Reader has been available and, as msp packages, regular updates accordingly.

Today I found the enterprise Homepage and got a:
AcroRdrDCx642200120085_MUI.exe
from https://get.adobe.com/de/reader/enterprise/

However, it only contains an AcroPro.msi and no AcroRead.msi as in the 32-bit version.
So far, I update the package via the slipstream integration and then distribute the package via the software distribution of the GPO.

Can I use the AcroPro.msi in the same way, or does this require a licence or a different procedure?

Many thanks
