Adobe Support got back to him promptly, but as of October 27, 2021, the case was still unresolved. Karl asks Adobe Support to review the process. It installs Acrobat DC instead of Acrobat Reader DC. The download of Adobe Acrobat Reader DC (21.007.20099) 64 bit contains the wrong application. On October 13, 2021, Karl complains that the download of 64-bit Adobe Acrobat Reader DC (21.007.20099) delivered the wrong application, Acrobat DC. I have thereby assembled certain posts in the following screenshot. I came across the issue via the following tweet from blog reader Karl.
