Cannot install Acrobat Reader with Acrobat Pro

[JR Boulay]

Hello

To remove some bugs in Acrobat Pro I followed the Adobe procedure: uninstall Acrobat and then use the AcroCleaner.
It took me several hours but it didn't fix any of the concerned bugs.

When I reinstalled Acrobat Pro (64 bits) I got a message telling me that Acrobat Reader (32 bits) would be uninstalled, which was done.

The problem is that now I can't reinstall Acrobat Reader, each time the installation ends on this truncated and incomplete message (attached) which seems to say that Acrobat Reader is already installed.

It says : "Old/new version of Acrobat already in........"

What can I do?

I'm a developer of PDF forms and I absolutely need to have Acrobat Reader to test them.

Thank you for your help.

This thread is redundant and should be closed or at least this comment pinned as the 'solution'. Adobe have provided an official solution to this that works and I use now across dozens of my clients (I am a senior network engineer and work for an MSP that deals with hundres of different clients and environments). Installing side-by-side does NOT work for most scenarios as suggested by multiple people/'Adobe employees' in this thread. 

Adobe's actual solution is to install the '64-bit Unified App Installer' and add the registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown:“bIsSCReducedModeEnforcedEx”=dword:00000001

(This will default Acrobat to run in 'Reader mode' by default but automatically enable full Acrobat features when signing in)
