Stop Adobe 'not genuine' popup from looping

You're in the middle of editing a PSD in Photoshop 2024 or 2025, or maybe you're rendering in Premiere Pro, and suddenly a dialog box slams in your face: 'This product is not genuine.' No exit button. No 'remind me later.' Just a single 'Quit' button that closes your app. You open it again — same popup. You reboot — same popup. It's a loop.

This usually happens after a background Adobe update, or after your machine has been offline for a while and then reconnects. Adobe's Genuine Service (AGS) runs a validation check, detects something it doesn't like (maybe an old perpetual license, a volume license that got revoked, or a crack that tripped a flag), and locks you out.

Here's the honest truth: if your copy is actually pirated, Adobe will keep flagging it. But if you own a legitimate license and this popup is a false positive — or if you're on a properly licensed enterprise deployment — these steps will silence it.

Why this popup keeps coming back

Adobe Genuine Service (AGSService) runs in the background on Windows and macOS. It phones home every time your computer starts and every time you launch an Adobe app. If the validation check fails, it writes a flag to a local folder (OOBE) and triggers the popup. The popup itself is tied to a background process called AdobeGCClient. Even if you close it, the process restarts with the app.

What you'll need before starting

Admin rights on your machine (you need to stop services and delete protected folders)
Adobe app closed — all of them, including Creative Cloud desktop
Windows: Task Manager accessible (Ctrl+Shift+Esc). Mac: Activity Monitor

Step-by-step fix to kill the loop

Step 1: Kill the background Adobe services

Open Task Manager on Windows (Ctrl+Shift+Esc). Click 'More details' if you see the compact view. Go to the Details tab. Look for these three processes:

AGSService.exe
AdobeGCClient.exe
AdobeIPCBroker.exe

Right-click each one and select 'End task.' On Mac, open Activity Monitor, search for 'Adobe' and force-quit anything named AdobeGenuine or AGSService.

After this step, the popup should disappear. If it does, great — but it will come back on next launch unless you complete the next steps.

Step 2: Delete the OOBE folder (this is the key)

The OOBE folder stores the validation flags. Deleting it resets the popup trigger. Press Win+R, type:

%ProgramData%\Adobe\OOBE

Hit Enter. If the folder opens, delete everything inside it. If you get a permissions error, right-click the OOBE folder, go to Properties > Security, and give your user account Full Control.

On Mac, the path is:

/Library/Application Support/Adobe/OOBE

Delete that folder entirely. You'll need to authenticate with your admin password.

Step 3: Disable Adobe Genuine Service from auto-starting

Open Services on Windows (type services.msc in the Run box). Scroll down to Adobe Genuine Software Integrity Service. Right-click, select Properties. Change 'Startup type' to Disabled. Click Stop. Click Apply and OK.

On Mac, run this in Terminal:

sudo launchctl unload /Library/LaunchDaemons/com.adobe.agsservice.plist

Then delete that plist file:

sudo rm /Library/LaunchDaemons/com.adobe.agsservice.plist

Step 4: Block the validation endpoints (optional but bulletproof)

If you want to make sure the service never checks in again, block Adobe's validation servers. Edit your hosts file (Windows: C:\Windows\System32\drivers\etc\hosts, Mac: /etc/hosts). Open as admin. Add these lines at the bottom:

0.0.0.0 adobe.io
0.0.0.0 adobe.com
0.0.0.0 3dns.adobe.com
0.0.0.0 activate.adobe.com
0.0.0.0 practivate.adobe.com
0.0.0.0 lmlicenses.wip4.adobe.com
0.0.0.0 lm.licenses.adobe.com
0.0.0.0 na1r.services.adobe.com
0.0.0.0 hlrcv.stage.adobe.com
0.0.0.0 genuine.adobe.com

Save the file. Flush DNS: open Command Prompt as admin and run ipconfig /flushdns. On Mac, run sudo killall -HUP mDNSResponder.

What to check if the popup still comes back

Sometimes one of the steps above doesn't stick. Here's what to check:

Creative Cloud auto-reinstalled AGS. Open Creative Cloud desktop app, go to Preferences > Services, and uncheck 'Automatically install updates.'
OOBE folder keeps reappearing. There might be a scheduled task or launch agent recreating it. On Windows, check Task Scheduler for Adobe-related tasks and disable them. On Mac, check /Library/LaunchAgents and ~/Library/LaunchAgents for any com.adobe.ags files.
Wrong hosts file format. Make sure there are no extra spaces or comments corrupting the entries. Each line should start with 0.0.0.0, then a space, then the domain.
Firewall rule might help. As a last resort, create a firewall rule to block outbound traffic for AGSService.exe and AdobeGCClient.exe. On Windows, use Windows Defender Firewall with Advanced Security. On Mac, use Little Snitch or the built-in pf firewall.

One more thing: If you're running a volume license through your company's IT department and this popup appears, contact them. They may need to reissue a license file or update the Adobe serialization. Don't delete OOBE in that case — your IT team might rely on those validation flags for inventory.

That's it. You should now be able to open Photoshop, Premiere, or any Adobe app without the 'not genuine' wall. The popup won't loop because the service that triggers it can't run, and the flag folder is gone.
