I have a Mac running Seqouia 15.  I installed Adobe Acrobat Pro 2020 on it and attempted to enter my license key.  After enter the key, Adobe wants me to sign in.  When I sign in, I get the following message: Acrobat Licensing Application quit Unexpectedly.  It is just continuous loop of Adobe wanting me to sign in and Licensing Application quiting Unexpectedly.

I am having a very similar problem. I migrated to a M4 Mac Mini running Sequoia about a week ago. When I first finished the migration I opened Acrobat Pro 2020 to make sure it worked. I think that I had to sign back into my Adobe account but it worked fine afterwards. Now a week later after rebooting my Mac whenever I try to open the app directly or double click a .pdf file I get the Signed In Required dialog box. I type in the email and password of my Adobe account the dialog goes away but Acrobat 2020 does not open. I try opening it again but get the same sign in popup. I don't understand this because it worked last week. I can launch and sign in to the Creative Cloud app using the same email and password but it doesn't show anything about my 2020 license.

I was able to resolve my issue with the help of ChatGPT. It told me to go and log in to my Adobe account using a web browser. I went to the Products page under my account. Copied the serial number and re-downloaded the installer. I then reinstalled Acrobat 2020. After I reinstalled I went to open the application again and it brought up a sign in dialog again. However what I noticed is that the dialog looked different from before. The new 2020 license dialog did not have the exact same layout and format when I was trying it before. It did look like the sign in dialog for Creative Cloud though. So I surmise that Adobe rewrote/modified the license sign in app and the older version of it is incompatible with their current license system.

I followed your steps and re-downloaded the installer. However, when I clicked it, it won't install, and stuck at the "Read Me" step. Any solution please?

I have the same issue on my Mac.


Installation of acrobat 2020 with license key no longer runs. I'm prompted to login to Adobe account then the App quits.  

I tried an uninstall and clean install with entry of my Acrobat 2020 license key. But still the same issue.

 

Acrobat 2020 App installs OK but it just quits when I sign-in to Adobe account.

Same.  M4 macOS 15.3.2 nets blank "Acrobat Licensing Application" window hang.  Tried the OOBE (1 & 2) suggestions, install/reinstall, AcroClean tool, and no resolution.  

 

So, off to Console.app I went, and summary:  looks like code signing issue.

 

See attached log.  Some entries are:

 

error 21:06:46.430949-0400 trustd SecKeyVerifySignature failed: Error Domain=NSOSStatusErrorDomain Code=-67808 "RSA signature verification failed, no match" UserInfo={numberOfErrorsDeep=0, NSDescription=RSA signature verification failed, no match}

Same issue for me BTW with Acrobat Pro 2017 on an Intel MacBook Pro, with Sequoia 15.3.1: Acrobat Licensing Application quit unexpectedly after successful login with Adobe ID. Tried all suggestions posted here to no avail.

ChatGPT suggested that the licensing crash is due to the Acrobat Pro 2017 32-bit licensing system being incompatible with newer macOS. I was trying on my 2019 MacBook Pro. I pulled out my old 2015 MacBook, which I had originally used for Acrobat, and I was able to log in. It then asked for the serial again, but then I got:

 

> The serial number you have entered has been revoked. This product cannot be licensed. Please click here to resolve this issue.

 

When I click on the link, I get:

> The Adobe serial number you entered is invalid It may be blocked due to misuse – or because we no longer support new activations of outdated software and apps. Upgrade your Adobe app or start a free trial to get the latest features and functionality.

 

I'm guessing 2017 is no longer usable now. 😞

Hi @Ron31407832j75x,

 

Hope you are doing well. Sorry for the trouble.

 

Would you mind trying and providing permissions to the OOBE folder for the licensing app to run?

 

To do so:

  • Quit the Acrobat Licensing Application and Acrobat.
  • Open Terminal and type the following command:
chmod 777 /Users/<your_username>/Library/Application Support/Adobe/OOBE/

Once done, restart your computer.

 

Hope this helps.

Hi I  upgraded my older MacBook Pro (intel) to Sequoia and my Adobe Acrobat version 15.006.30527 kept working. I then migrated my system to a new Mac Mini M4 and am having this same problem. I used the terminal command :

chmod 777 /Users/<your_username>/Library/Application\ Support/Adobe/OOBE/

 I then tried : 

chmod -R 777 /Users/<your_username>/Library/Application\ Support/Adobe/OOBE/

and it still did not work.  

Acrobat Licensing Application runs and I get  the Account Access Notification on my iPhone which I approve , but then Acrobat Licensing Application quits and Acrobat does not startup. It could be a permissions error on the Acrobat app, or on another file that Acrobat Licensing Application is writing to.

Hi Souvik,

I collected Adobe CC logs: File: AdobeLogs_20241203_084145_552-mac-GS.zxp

I'm not sure which Console Network Logs you want, there are alot - but here is the one that gets created when my Adobe Account Login Fails. Let me know if you need others.

Thanks for your help with this.

Roy

 


Thanks, @Roy_Smith,

 

I have forwarded this to the devs. 

 

Please allow me some time to get this investigated.
