Failed Acrobat installation error 136 MacOS 10.15

[earl_8748]

Upgraded an iMac 21.5-inch Late 2013 Intel Core i5 from MacOS 10.14.6 Mojave to 10.15.7 Catalina, then attempted to undate Adobe Acrobat under my Adobe Creative Cloud panel only to get an update failure at about 46% progress.  Tried multiple times, and on a clean user login, to no avail. The used the unistall feature to remove the existing Acrobat version to try a clean install, but same results on the install, and now I have no Acrobat at all. Have searched the posts, but very few Macintosh posts and none that are recent.

@earl_8748 When an install fails at a certain percentage, it often leaves behind corrupted or incomplete files that interfere with subsequent attempts. Even using the uninstaller through Creative Cloud might not remove everything. This is a very common cause of "Error 136." In this case, I would suggest downloading Adobe Cleaner (straight from Adobe's website, and not a third-party site for this). The Adobe Creative Cloud Cleaner tool can fix many common problems (such as removing old Adobe software, cleaning corrupt installation files). 

Once you have uninstalled the Acrobat install files with Adobe Cleaner, I would go back to adobe.com and install the Creative Cloud app and try to install Adobe Acrobat again through the Creative Cloud app. You might find older versions (if that's what you're licensed for) as direct downloads that sometimes have different installation behaviors.
