You're just trying to get some work done. Or maybe you're midway through a game. Then, out of nowhere, a window flashes. It’s the download occ pop up. It disappears before you can even read it. Or worse, it hangs there like an uninvited guest, demanding you "Open," "Save," or "Cancel" a file you never asked for in the first place.
It's annoying. Actually, it's more than annoying—it feels sketchy.
Most people assume they've been hacked the second they see an unexpected download prompt. While caution is good, the reality is usually a bit more mundane, though still something you need to handle. Usually, this specific pop-up is tied to the Oracle Cloud Client (OCC) or similar enterprise-level background processes that have lost their way. It’s basically a handshake between your computer and a server that didn't go as planned.
What Is This Thing Anyway?
The "OCC" in the download occ pop up typically refers to the Oracle Cloud Commerce environment or the Oracle Content Capture tool. If you work for a large company, your IT department might have pushed an update that is failing to authenticate. When the authentication fails, the browser doesn't know what to do with the data packet it just received. So, it does the only thing it knows how to do: it asks you to download it.
Wait.
Don't click "Open."
If you aren't actively trying to download a file, clicking that button is like opening your front door to a stranger just because they knocked loudly. Even if it's a "legitimate" broken process from a real company like Oracle, downloading corrupted or partial script files can mess with your browser's stability.
Sometimes, this happens because of a misconfigured MIME type. In plain English, the server is sending a file but telling your browser, "Hey, I don't know what this is," and your browser responds by offering to save it. It’s a classic breakdown in communication. You see it a lot in legacy business environments where old software is forced to play nice with modern versions of Chrome or Edge.
Why Does It Keep Coming Back?
Persistence is the hallmark of a bad configuration. You close it. It returns ten minutes later. This happens because most of these "OCC" triggers are set on a timer.
Many enterprise applications use a "heartbeat" signal. The app checks in with the mothership every few minutes to see if there are updates or to verify your login credentials. If that check-in results in a download occ pop up, it’s because the server sent back a file instead of a simple "OK" signal.
Is it malware? Honestly, usually not. But hackers are smart. They know that if a user gets used to seeing a specific pop-up, they eventually get "click fatigue." You get so tired of closing the window that you eventually just click "OK" to make it go away. That is exactly what a bad actor wants. This is why we have to kill the root cause rather than just playing whack-a-mole with the "X" button.
Check Your Browser Extensions
Extensions are the most common culprits for rogue pop-ups.
Open your browser's extension manager. Look for anything related to Oracle, "Capture," or "Cloud." If you didn't install it personally, or if you don't use it for work, disable it. Immediately.
I’ve seen cases where a perfectly normal extension gets sold to a new developer, and suddenly it’s pushing weird download requests to thousands of users. It’s a bait-and-switch. You think you’re using a "Dark Mode" toggle, but the extension is actually trying to pull data from an OCC endpoint.
The Connection to Adobe and Oracle
Interestingly, a lot of people see the download occ pop up when using Adobe products or specific PDF viewers integrated into their workflow. Oracle and Adobe often share a backend infrastructure in corporate settings. If you’re using an outdated version of Adobe Acrobat that’s trying to sync with an Oracle-based document management system, you’re in for a world of pop-up pain.
The fix here isn't fancy. It's boring. Update everything.
Go to the Help menu in your software and check for updates. If you're on a managed work computer, you might need to nag your IT person. Tell them the "Oracle Cloud Client handshake is failing." They'll think you’re a genius, and they’ll actually look into the server-side configuration.
Clearing the Ghost in the Machine
If the updates don't work, you have to get aggressive with your cache.
Your browser remembers things. Sometimes it remembers the wrong things. If it has cached a "partial" download of that OCC file, it might keep trying to "resume" it every time you open a new tab.
- Go to your browser settings.
- Find "Privacy and Security."
- Clear your browsing data, specifically Cookies and Cached images and files.
- Restart the browser.
It feels like the "unplug it and plug it back in" of the internet world, but for the download occ pop up, it actually works more often than not. You’re essentially wiping the slate clean so the browser stops trying to finish a conversation that started three days ago.
Stopping the Pop-Up on Mac vs. Windows
Windows users usually see this as a small box in the bottom corner of their screen or a prompt from the "Downloads" folder. On a Mac, it often manifests as a "file.occ" appearing on the desktop or a sudden prompt in Safari.
On Windows, check your Task Manager (Ctrl + Shift + Esc). Look for any processes named "OCC," "Oracle," or "Cloud Capture." If you see one that is consuming a weird amount of CPU, right-click it and select "Open file location." This will tell you exactly where the culprit is hiding on your hard drive. If it's in a Temp folder, it's likely a rogue process you can safely terminate and delete.
Mac users should look at their Activity Monitor. Look under the "Network" tab. Is there a specific process sending or receiving a lot of data right when the pop-up appears? That’s your smoking gun.

Identify the Source
The next time the pop-up appears, do not close it immediately. Look at the URL or the file path. Does it mention a specific website you have open? If it says something like static.oracle.com or workflow.companyname.com, you know it’s a site-specific issue. Stop visiting that site or contact their support.
Audit Your Startup Apps
Many of these download triggers start the moment you turn on your computer.
- On Windows: Go to Settings > Apps > Startup.
- On Mac: Go to System Settings > General > Login Items.
Toggle off anything you don't recognize, especially anything with "Cloud" or "Capture" in the name.
Reset Your Browser Settings
If the pop-up persists across different websites, your browser settings might be hijacked or corrupted. Most browsers have a "Reset Settings" button that returns everything to factory defaults without deleting your bookmarks. This is the "nuclear option" for stopping the download occ pop up if it's caused by a deep-seated configuration error.
Update Your Java Runtime
Since Oracle is the king of Java, many OCC errors are actually just Java errors in a trench coat. If you have an old version of the Java Runtime Environment (JRE) on your machine, it might be struggling to handle modern web requests. Download the latest version from the official Java website and uninstall any versions that look like they belong in 2015.
Check for Malware
While we said it’s usually a configuration error, you can't be too safe. Run a scan with a reputable tool like Malwarebytes. Sometimes, what looks like an Oracle pop-up is actually a "browser hijacker" trying to redirect your traffic. If the scan comes back clean, you can go back to blaming a poorly configured server.
Final Sanity Check
If you are working in a corporate environment and none of this works, the issue is likely server-side. This means there is nothing you can do on your laptop to fix it. The IT team needs to fix the "Content-Disposition" header on their server. Send them a screenshot of the pop-up and tell them it appears to be a misconfigured MIME type for OCC files. They will handle the rest.
By following these steps, you move from being a victim of a ghost download to being the person in control of your workspace. No more random windows. No more mystery files. Just a clean, quiet desktop.
