Lightroom 6 - Sign in required

Community Beginner ,
Jan 22, 2021 Jan 22, 2021

Dear community,

Today as often clickedon the LR shortcut towork on my photo but instead of launching normaly, I had the "Adobe Phtoshop Lightroom 6 Sign In " pop up. Than it directly goes to the Phtoshop Lightroom 6 Trial window. I click on License this software, put my Serial Number (bought in 2017) click on "Next" but instead of going to the next step, it reload the "Adobe Phtoshop Lightroom 6 Sign In " pop up.

Did not try to uninstall the software as I am not sure it will help and not sure I won t loose my catalog.

Any clue, on what happened?

Thanks,

Chris

I can confirm on the same; endless trouble getting LR6 activated using Brave. But with Firefox it went through the first time; LR6 successfully activated!! Now I'll be trying to get my CS6 software activated...


What a mess is Adobe putting us - legit purchasers of LR/PS who don't need the latest functionality and don't want to be forced into a subscription model - through... And that only because I'm upgrading to a new laptop...

@YoWilly  

Try the offline activation for LR6.x as described as Solutionj 2 in the linked document.

https://helpx.adobe.com/creative-suite/kb/serial-number-validation-launching-cs6.html

 

But be aware: if you have reached your activation limit and you don't have any chance to deactivate an older installation you're out of luck. Adobe has stopped the support of Lightroom 6 and the resetting of the actiovation counter isn't possible anymore.

 

My System: Intel i7-8700K - 64GB RAM - NVidia Geforce RTX 3060 - Windows 11 Pro 24H2 -- LR-Classic 14 - Photoshop 26 - Nik Collection 8 - PureRAW 5 - Topaz PhotoAI 4

Hi @AxelMatt,

 

I got LR 6 working, but ran into the activation limit trying to install CS6; totally forgot to deactivate CS6 on my old laptop (which is already formatted with Windows reinstalled for the next user...) I may have to dig up my old backups to see if I have an image that includes CS6 ...

I managed to restore an old image and deactivated CS6 Photoshop to pass the Activation Limit. I successfully managed to activate CS6 following the same steps as described by @Eldiin for LR6 and using FireFox....

I got it to work using Firefox (failed with Edge and Chrome). It still failed once but didn't get into a loop.

Hi, Thanks for your support. Unfortunately I can't lauch lightroom 6: when I click on the app-icon it keeps loading (also when my internet is running). So step 2 I can't complete. Do you have any suggestions what could be the case? I have lightroom 6 installed (CD version). It all of a sudden doesn't work anymore. Already checked for locked database. This isn't the case. Hope you know what to do (I work on a macbook MacOS Mojave 10.14.6)

 

I found information on my macbook that said: Lightroom is outdated software because of the 32bit thing, but I haven't updated my macbook for a long time now. So that shouldn't be the problem

Any thoughts? Thanks in advance, Ingrid

In my case I also had to install Adobe Creative Cloud before my installation would complete.  Of course CC didn't exist when LR6 was released so it isn't on your CD and LR6 doesn't know it needs it, but I think that the license key will not get verified without it.  You can install CC from Adobe's website.

It is my understanding that installing the current Adobe Create Cloud application is not needed for (and probably will prevent) successful installation of Lr 6. All the files you need to install Lr 6 should be in the Lr 6 installer file.

That was my understanding too, but for me it simply would not pass the license verification stage even using the process described in this thread.  

 

I didn't have the CD, I was installing from a downloaded installation package I have saved from the last time I needed to install Lightroom 6.  Anyway -- I only mention it because it worked for me.

@SUB Photo 

Surprise, you were able to install Lr 6 using some method I have not seen mentioned before 😮

Can you remember and tell us the exact steps you followed?

Hello, I disconnected from the internet and then installed LR 6 from the disk. Got to window that said "no internect" choice was Retry or Connect Later. I went to the offline activation website and I get to the screen to enter the Response Code and Serial Number but I never saw where to generate the Request Code. I did select Connect Later and it let the program install and I can use it as long as I am not connected to the internet. Any ideas? Thank you.

Some people report that using the Firefox browser works better when you get to the part where you have to enter your response code.

Thank you!  Have spent quite a bit of time trying to figure this out this afternoon after setting up a new laptop and digging out my old Lightroom Classic disc and finding my upgrade serials.

I wrote the steps everyone has been commenting on,  to try and bring some kind of clarity and joy back to people who might end up falling into the same loops and issues I was, when activating Classic Lightroom 6 Desktop, because Adobe refuses to help people with legitamient purchases, if Adobe no longer supports the product. Support will try to upsell to you. They do this in hopes to drive users to their only active model... the subscription based cloud platform. Because one time purchases don't generate steady profits for them. Subscriptions do. It's frustrating. It's mind-numbing to try and get this product activated. And the fear I have is that at some point, even these steps won't help.

I do want to add some additional steps, but cannot edit my original comment. After 8 months of posting, I am now at it again, trying to install this product.

Brave and Chrome just refuse to work. Moved to Firefox. It seems this worked better for others. What I observed, however, is after getting to the point where I needed to generate a response code (regardless of browser); I would enter the request code I generated from Lightroom, then enter my Serial number, and then it would try to auto-submit the request to get the response code, EVEN THOUGH there's a big "Generate Response Code" button.

When it would try to auto-submit, every time it would come back saying the session expired and would want me to log-in again. Would get into this never ending loop. It just wasn't working.

However, a thought came to me... what if I try to click the button before the auto-submit happens? It didn't work. Another thought came to me... what if I try to click the button a bunch of times, to try and overwrite the auto-submission? Would that even work?

Well, I can tell you, for me, it did. I spam clicked that button until it took me to a page with the response code.

Hope this helps someone out there. I'm mainly putting this here in case I have to do it again, to help me remember what I did.

Just so everyone understands. The page to generate the response code changed from when I did it to now... Not sure when. When I first wrote the steps on the first page, the page did not auto-submit. You had to click the button. Now it auto-submits. It's subtle and easy to miss. But if you look immediately to the right of your serial number, after entering all the pieces necessary, you'll see a circle going around. Even if you hit the generate response code button once... the auto-submit will happen regardless and if you are unaware, it will give off the the idea that clicking the button does nothing. Spam click the button instead.
