Same problem here. 

Since 2016 I generate my update packages on the "Base-EXE" and use slipstream integration with the latest update file.
But this month the installation on my clients failed with:

Product: Adobe Acrobat Reader DC MUI -- Error 1722.There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action InstallWebResources, location: C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroCEF\RdrServicesUpdater.exe, command: 21.001.20135 20.013.20074.0

Product: Adobe Acrobat Reader DC MUI -- Configuration failed.

I tried to update my clients (automatically install over the 20.013.20074.0) and I tried to do a fresh installation with an new client.
