P: Can't launch the most recent update of Lightroom Classic

[Terry28393220wu8l]

HELP - I downloaded and installed the latest upgrade to Lightroom Classic and it will not launch. I have uninstaleld it - twice - shut down my Mac computer, restarted and then tried to install the program. Nothing works. Until the new upgrade, it worked perfectly...suggestions??

Thanks,

Terry

I just upgraded the Monterey to 12.6.5.  I do not have a clue why 'System Integrity Protection' is disabled. Could some other app have done that? As you' ve guessed by now that I am no tech wonder, I certainly did not disable it 😞

Is the latest LR too much for my mac?

The GPU just meets the minimum requirements (i.e. 2GB). Therefore, LrC should work, although the AI based features (Masks, Denoise and Export) will be slow/laggy.

You mentioned that you'd updated to 12.6.5. Did this help?  If not (I suspect not), then can you tell us when it last launched without a crash and what has changed between the last time LrC launched without crashing and now.

Unfortunately the new Monterey did not help (I also re-installed LR again, to no avail).  LR worked fine yesterday. I think also yesterday my CC updated Photoshop, CameraRaw and AE. I remember now that when I started up Photoshop today I got a pop-up warning saying something about the 'generator'. I closed it before I realised what it said. Does this help?

[fran 65]

Thanks, I tried but it seems I have no permission to change that 😞

[fran 65]

Which is totally weird since I had to use my computer password and still couldn't get it changed 😕

[Ian Lyons]

The Photoshop popup is probably related to the Generator Plugins. It's unlikely that this would have affected LrC. That being said, Creative Cloud updating other apps may have changed something shared with LrC. The only thing I can think of on that front is the GPU compatibility check.

On the off chance that the GPU is causing the crash. You should check whether the following helps

1. Locate the Camera Raw GPU Config.txt file.

   • (macOS) /Users/[user name]/Library/Application Support/Adobe/CameraRaw/GPU/Adobe Photoshop Lightroom Classic/Camera Raw GPU Config.txt

   The user Library folder is hidden by default in macOS X 10.7 and later releases. Use the directions here.

2. Manually delete the Camera Raw GPU Config.txt file.

   3. Launch Lightroom Classic.

   Others experiencing crashes at launch have reported that reverting to LrC 12.2.1 helps, but let's first check whether it's the GPU tests that are at fault.

This looks like an OS crash dialog and not Adobe's. This means it won't be in our system as it was sent to Apple.

I deleted the file, but didn't help. LR crashed at startup.

[fran 65]

It worked!! I tried it again and LR started up!!  Thank you!!

[fran 65]

I tried to change the permission for the file described by Heinero, down below, and it worked! It started!

That's the same fix as described by Adobe's Smit K in this thread https://community.adobe.com/t5/lightroom-classic-bugs/p-can-t-launch-the-most-recent-update-of-light...

[Ian Lyons]

@Rikk Flohr: Photography  Since the issue raised in this thread was resolved using the same fix as Smit K provided in https://community.adobe.com/t5/lightroom-classic-bugs/p-can-t-launch-the-most-recent-update-of-light... then I think it would be beneficial to merge the two threads.

I have a major issue on lightroom classic.
first my setup : MAC BOOK PRO M1 PRO VENTURA 13.3.1, 32g RAM, 2TO SSD

Lightroom classic latest version.

Lightroom refuse to lunch. I lightroom icon appears for 1 or 2 second in my dock and then disapear.  

Photoshop is ok as the other software of my package. Only lightroom classic as all of you

I have uninstall Lightroom, delete the files, I have tried to open old catalogs. Same issue. Permissions were already on Read & Write.
I have attached screenshots. 

I want to precise it was also before I upgrade to Ventura.

Do you how I can get the older version of lightroom? 

Also I do not have any crash reports. Nothing shows up

[Modernis]

Also,

Unlike others, installing older of lightroom classic versions is not helping. Same issue.

After installing older version the icon on the dock just last 5/6 seconds the first time I try to lunch it after instal. When I try to lunch it for a second try then the icon just 1 second, as before with the 13 version

I have updated the LrC to 12.3 and my computer Mac Studio is updated to macOS Ventura 13.4. Apple M1 Ultra 64GB RAM. 

My LrC won´t even start, I can just see a glimps of a picture and the crash window report. Any suggestion, or possible solution appreciated. I have already try to re-install the LrC, didn´t work. Thanks a lot in advance.

Does this look like the same issue: https://community.adobe.com/t5/lightroom-classic-discussions/can-t-launch-the-most-recent-update-of-... 

[Diego Espin]

In deed. I just see your post. I tried all the solutions proposed. It does not work. I try re-installing, changing the access rights to the /library folders (although they are not located as indicated in the solution, the library folder is a main folder not under a user). Anyways.. it just can´t start up.

Unfortunately, this does not help in my case. Thanks tho.

@Diego Espin There is an update to macOS Ventura 13.4.1, Have you tried to see if it helps?

[Diego Espin]

Yes, I have. My machine is fully updated to macOS Ventura 13.4 (22F66). There is no more available updates.

[DdeGannes]

There is macOS Ventura 13.4.1

Changing the permissions to Read & Write in the Library Log flolders and Adobe Log folders worked for me.

LeC 12.3 startet auf meinem MacStudio MacOS  13.3.1 nicht.
nach dem Start kommt sofort eine Feherlmeldung.
nach einem Rückfall auf LrC 12.2.1 startet LrC sofort wieder, mehrfach probiert.
