Backing Out / Reverting to a previous version

Hi

I have posted the following question in 2 places -

http://blogs.adobe.com/photoshopdotco...

and

http://feedback.photoshop.com/photosh...

and NOT yet received a reply.

The question is

Backing out an Update to Photoshop CC - what is the Adobe recommended process ? I ask because I see some folks saying 14.2 has broken a few things ( http://blogs.adobe.com/photoshopdotco... ) , so before I think about updating, I need to know what the process to back-out is. I'm on Windows 8.1 ; At a guess, I'd be looking at backing up Program Files/Adobe, Program Data/Adobe, and Users/"my user"/AppData/Roaming/Adobe & Local/Adobe. Thanks . . .

PLEASE can I have a reply indicating what the correct back-out process is (being able to back-out is standard IT procedure).

Thanks

AFAIK, Adobe doesn't provide a mechanism for installing or reverting to a previous version, which I think is what you're asking to do.

There may be some way to peek at what the Adobe Application Manager (AAM) is downloading for an update and save that file or set of files so you can re-run which ever set you want, after completely uninstalling the application. But if you have not saved off the previous 4.1.2 installer then you don't have a way to do this, this time.

The normal Windows mechanism for reversing a system change like a program install is to create a restore point just prior to the install, and then restore back to that if you don't like what the install has done. This will undo the changes to program files by restoring from a backup of programs and system-configuration whenever the last restore-point was made prior to the install. It would not undo your changes to saved PS documents nor probably changes to your preferences files.

The way to get to System Restore on my Windows 8.1 computer is right-click on the new-to-Win81 Start flag at the left or top of the task bar, choose System, then System Protection, which should let you both create a restore point and restore back to a previous one.

If you're not sure this will work, then imaging your entire computer with a third-party product and then restoring it from that image backup should work.

Experimenting with a virtual machine that allows snapshots to be done can help work out the entire process if you're not sure, but you'd need extra Windows licenses to install to a VM.

Yes that is what I'm asking, and I think it's a very necessary procedure to have. I don't have (& really don't need) the VM capability for anything else, & Imaging my C drive is definitely too restrictive as a Restore will reverse changes to other apps in normal daily use, which might also apply if using the Windows Restore Point point process . . . so I think it's a problem that needs to be fixed. As I said, being able to backout (without affecting any other apps) is a standard IT expectation, and it seems Adobe is lacking in this basic aspect. It should only be a bit of documentation, I'm not asking for any automation -

Surely the engineers must know what files are potentially going to be updated . . . I know people (in other software) fields who are involved in Production software upgrades, and they check the target files every time a change is made. Thanks . . .
