How to Fix Zoom Error Code 10004 (Update Failed)

Zoom error code 10004 means the Zoom app could not reach Zoom's servers to check for or install an update. To fix it, check Zoom's service status, make sure your internet works, allow Zoom through your firewall or antivirus, and reinstall the latest version from Zoom's website. One of these steps fixes the error for most people.

If you have a meeting right now, you can usually still join from a web browser at zoom.us or from the Zoom app on your phone while you fix your computer.

7 ways to fix Zoom error code 10004

1. Check if Zoom is down

Go to status.zoom.us. If Zoom shows an outage, the error is on their end. Wait a little while and try again.

2. Check your internet connection

• Open a website to make sure you are online.
• Restart your router and modem.
• Try a different network, like your phone's hotspot.

If your connection is slow or keeps dropping, see our guides on fixing slow internet and Wi-Fi that will not connect.

3. Restart Zoom and your computer

Quit Zoom fully, then restart your computer. On Windows, right-click the Zoom icon near the clock and choose Exit. On Mac, choose Zoom in the menu bar, then Quit.

4. Allow Zoom through your firewall

On Windows:

1. Open Windows Security, then Firewall & network protection.
2. Click Allow an app through firewall.
3. Click Change settings, find Zoom, and check both Private and Public.
4. Click OK and open Zoom again.

On Mac: Go to System Settings, then Network, then Firewall, then Options, and make sure Zoom is allowed to receive connections.

5. Pause antivirus or VPN for a moment

Some antivirus programs and VPNs block Zoom's update servers. Pause them briefly, try the update, then turn them back on. If that fixes it, add Zoom to your antivirus's allowed list.

6. Update Zoom manually

In the Zoom app, click your profile picture, then Check for Updates. If that fails with 10004, go to the next step.

7. Uninstall and reinstall Zoom

1. Uninstall Zoom. On Windows, go to Settings, then Apps, find Zoom, and click Uninstall. On Mac, open Zoom, click zoom.us in the menu bar, and choose Uninstall Zoom.
2. Restart your computer.
3. Download the latest version from the official Zoom download page at zoom.us/download.
4. Install it and sign in.

Your meetings and settings are saved to your account, so you will not lose them.

Quick checklist

On a work or school computer?

Many offices and schools control software updates. If you cannot change firewall settings or install software, contact your IT help desk. They may need to update Zoom for you.

Is your computer slow too?

If Zoom freezes or lags even after the fix, your computer may be short on memory. Our guide on making a slow laptop faster has easy tips.

Fixes by device

The steps above work on most computers, but each device has a few extra things to check.

Windows

• Run Zoom as an administrator once. Right-click the Zoom icon and choose Run as administrator, then check for updates. Some updates need extra permission to install.
• Check the date and time. If your computer clock is wrong, secure connections to Zoom's servers can fail. Go to Settings, then Time & language, and turn on Set time automatically.
• Clear space on your C: drive. Updates need room to download. If your drive is almost full, delete old downloads and empty the Recycle Bin.
• Install Windows updates. Old system files can cause install errors.

Mac

• Allow the installer. If macOS blocks it, go to System Settings, then Privacy & Security, and click Open Anyway next to the Zoom message.
• Move Zoom to the Applications folder. Running it from Downloads can cause update problems.
• Check your Mac's free space in System Settings, then General, then Storage.

iPhone and iPad

The Zoom app updates through the App Store, not inside Zoom. Open the App Store, tap your profile picture, and update Zoom from the list. If it will not update, delete the app and install it again.

Android

Open Google Play, search for Zoom Workplace, and tap Update. If it gets stuck, go to Settings, then Apps, then Google Play Store, and clear its cache.

What causes error 10004?

How to join a meeting right now

If you have a meeting in a few minutes, do not wait for the fix.

1. Use your browser. Open the meeting link and look for Join from your browser at the bottom of the page. It works in Chrome, Edge, Safari, and Firefox.
2. Use your phone. Install the Zoom app on your phone and join with the meeting ID and passcode.
3. Dial in by phone. Most meeting invites list a phone number you can call for audio only.

Then come back and fix the desktop app after the meeting.

Common mistakes to avoid

• Downloading Zoom from other websites. Only use the official Zoom download page. Fake installers can contain malware.
• Turning off your firewall for good. Pause it only for a moment, or better, add Zoom to the allowed list.
• Installing many copies. Uninstall the old version before you install a new one, so they do not conflict.
• Ignoring updates for months. Older Zoom versions may stop being able to join meetings at all. Turn on automatic updates if you can.

How to keep Zoom updating smoothly

• In the Zoom app, open Settings, then General, and turn on Automatically keep Zoom up to date.
• Restart your computer at least once a week.
• Keep a few GB of free space on your drive.
• Keep your antivirus updated so it recognizes Zoom as safe.

Why Zoom keeps asking you to update

Zoom does not let very old versions of the app join meetings for long. It sets a minimum version, and schools and companies can set their own, too. For example, the University of Wisconsin told its users that Zoom's minimum version moved up to 7.1.5 on August 21, 2026. When your app falls below the minimum, Zoom forces an update. If that update cannot reach Zoom's servers, you see error 10004.

So the real fix is to get the update through, using the steps above. Until then, the web version in your browser is not affected by the version rule.

How to check your Zoom version

On Windows or Mac:

1. Open the Zoom app and sign in.
2. Click your profile picture in the top corner.
3. Click Check for updates. Zoom shows your version and whether a newer one is ready.

On a phone or tablet: open the App Store or Google Play, search for Zoom, and tap Update if you see it.

Seeing error 10004 on a phone?

The error is most common on computers, but it can show up on phones too. Try these steps:

• Switch between Wi-Fi and mobile data to see if one works.
• Update Zoom from the app store instead of inside the app.
• Restart your phone, then open Zoom again.
• If nothing works, delete the app and install it fresh. Your meetings are saved in your Zoom account, not on the phone.

The bottom line

Zoom error code 10004 means the app could not reach Zoom's update servers. Check status.zoom.us, test your internet, and allow Zoom through your firewall, antivirus, and VPN. If it still fails, uninstall Zoom and download the latest version from zoom.us. Your meetings and settings will be waiting when you sign back in.
