I can’t reproduce your issue.
I used Munki to install Adobe Reader DC 24.003.20112. It installed seemingly successfully and launched normally.
Two things of note:
I use this Autopkg recipe to import Adobe Reader into Munki:
The recipe sets up a preinstall_script:
<key>preinstall_script</key>
<string>#!/bin/sh
if [ -e "/Applications/Adobe Acrobat Reader.app" ]; then
rm -r "/Applications/Adobe Acrobat Reader.app"
fi
if [ -e "/Applications/Adobe Acrobat Reader DC.app" ]; then
rm -r "/Applications/Adobe Acrobat Reader DC.app"
fi
exit 0
</string>
That simply removes any pre-existing app before installing the current one. Perhaps doing this will resolve your issue as well.
