"Update Required", "Sign in required" errors installing, updating, opening Photoshop Elements 2019

[bigdognj]

I am consistently getting an "Update Required" error message when and after attempting the most recent (July 2021) update to Camera Raw in Photoshop Elements 2019. After the update fails, I get a "Sign In Required" message when trying to start the program, followed by the same "Update Required" error when I try to sign in. I have tried to run the software on two different computers with the same result.

I got the same error when initially trying to install the package on a clean machine with latest Windows 10 updates installed. I had to install PSE15 first before I coul get the PSE2019 installation to complete.

The second machine is running an older Windows 10 version and I had been using PSE11 on it. I installed PSE15 first then ran the PSE2019 installer with no issues. Everything worked OK until attempting to run the Camera Raw update. This led to the same problems and I can'r run the editor anymore, although Organizer runs OK.

The upgrade file I downloaded from my account and am using is PhotoshopElements_2019_LS30_win64.exe. 

Below are the specs for my machine and screen shots of the error messages.

Please HELP

This is the message I got from the installer until I installed PSE15

Following the installation of PSE15, Photoshop 2019 installs successfully and everything seems to work. I then attempt to install the camera Raw update

and get this message:

From then on, I get thje following two errors whenever I try to run the editor. The update required error followqs the sign in request in an endless loop.

I'm having this exact same issue on a Windows 10 Home machine after a clean reinstall of Windows.  Premiere and Photoshop had worked on the machine previously, but now I can't get it to install.  The OS is completely updated and I have Internet Explorer 11 installed (as instructed) and I also have Edge and Chrome... but I still get the update error.

Does anyone have a fix for this?

Explained here. Options to set in IE. https://helpx.adobe.com/in/x-productkb/global/update-operating-system-and-browser.html

The link you provided is the same page that comes up when you click "Learn more" in the error dialog. Following the steps there didn't solve the problem. I even tried setting Internet Explorer as my default browser to no effect. Not sure why we're talking about Internet Explorer at all in 2021, but I completely disabled compatibility mode anyway. Any other thoughts?

[bigdognj]

BTW. I normally use Chrome as my default browser. Is Flash required for sign in? Flash player for Chrome has been discontinued.

[bigdognj]

Having had the thought about Flash, I tried Microsoft Edge as the default browser. Again no effect.

[Test Screen Name]

There is no Flash Player. This is about IE11, which is the engine used to show login pages. The default browser settings do not affect this. Were you able to follow all of the suggestions given in the instruction s for IE11?

[bigdognj]

Yes, I think. Disabled compatibility mode for everything. Couldn't find a legacy mode setting.

Has a solution been found yet? 
I experience the same problem on my PC.

download and install creative cloud for desktop.   You won't use it for anything- just download and install it, your problems will go away.

Would this help to solve my recognition problem of my serial number to do you think? See message below.

[Beau Gardeniers]

Unfortunately, still doesn't work.
I'm currently experiencing the problems with ADobe acrobat reader. I was thinking about buying Lightroom but not before I can fix the issue in the simple reader.

I ran into the same message while trying to update. Re-installed the latest version from the website and now my serial number isn't recognized anymore. Going from bad to worse. Adobe support points to the Forum to solve the issue, nice.

[Glenn 8675309]

Was your serial number you used for the latest version?  OR (soemthing like this)  You had PSE 2020, saw a download for PSE 2021, downloaded it, installed it, and then tried to use your old serial number in the latest version?

ABOUT THE SERIAL NUMBER: No it doesn't have anything to do with the serial number.

[Marius5C05]

Yes, it is still the 2020 version.

I started having the same issue with my Photoshop last night. It's an endless loop of the "Update Required" message and my browsers and system are all up to date. I even downloaded Internet Explorer to try and resolve the issue with no luck. I use PS and LR consistently and last night was the first time I experience this issue.

[defaultd90u1c56mt34]

I finally got it to work! It turns out my Creative Cloud app needed an update. Once I updated that on my desktop, it let me log in to PS and LR. The error message is very misleading.

[Marius5C05]

I do not have Creative Cloud. It seems you need to take a free subscription which automatically turns into a Monthly payment. I don't need Creative Cloud, I just want my standalone payed-for Elements 2020 to be licensed again. Strange situation.

[Glenn 8675309]

Just downlaod and install adobe creative cloud for desktop, you just need to install it, then you can basically forget about it.

How to download the Creative Cloud desktop app (adobe.com)   Nothing turns into a monthly payment unless you download a trial and don't cancel it (typically you would cancel it on day 6).

[Marius5C05]

@Glenn 8675309 , finally picked it up again. Installed Creative Cloud (without subscription) and updated the standalone Photoshop Elements and Premiere Elements. Unfortunately it still identifies my purchased serial numbers as invalid or expired. Standalone apps are not offered anymore so I wonder if starting a free trial of purchased membership would fix the issue?

Adobe service desk tried to resolve the problem but was finally not able to. Received new serial numbers and now everything was okay again.
