Zoom Error Code 10006 — What It Means & How to Fix It

What Does This Error Mean?

Zoom Error Code 10006 means the Zoom installer failed to complete. This error usually appears when you are trying to install or update Zoom and something interrupts the process. It is most often caused by leftover files from a previous install, insufficient permissions, or antivirus interference.

Affected Models

Zoom on Windows
Zoom on Mac

Common Causes

Leftover files from a previous Zoom installation are conflicting with the new install
Your antivirus or security software is blocking Zoom's installer from running
You do not have administrator rights on your computer
The Zoom installer download was corrupted or incomplete
A previous failed Zoom update left the application in a broken state

How to Fix It

Uninstall Zoom completely. Go to Control Panel > Programs > Uninstall a program, find Zoom, and uninstall it.

A standard uninstall alone is often not enough — leftover files must also be removed.
Delete any remaining Zoom folders. Check C:\Users\[YourName]\AppData\Roaming\Zoom and delete the folder if it exists.

AppData is a hidden folder. Press Windows+R, type %appdata%, and press Enter to open it.
Restart your computer. Then download the latest Zoom installer fresh from zoom.us/download.

Never reuse an old installer. Always download a fresh copy after a failed install.
Right-click the Zoom installer and choose 'Run as administrator' before installing.

Running as administrator gives the installer the permissions it needs to write files correctly.
Temporarily disable your antivirus while installing Zoom. Re-enable it once the install is complete.

Antivirus software sometimes blocks installer files incorrectly. Disabling it briefly allows the install to finish.

When to Call a Professional

Error 10006 is a DIY fix. If you are on a managed work computer and cannot install software yourself, contact your IT department. They may need to push the Zoom update through their management tools instead.

Frequently Asked Questions

Do I have to delete the AppData folder? Can't I just reinstall over the top?

Reinstalling over a broken install usually just re-triggers the same error. Deleting the leftover AppData folder gives the new install a completely clean slate. It takes about 30 seconds and makes a big difference.

I ran the installer as administrator and it still failed. What next?

Try disabling your antivirus completely before running the installer. If it still fails, download the Zoom MSI installer instead of the standard EXE. The MSI version is available at zoom.us/download and is sometimes more reliable on managed PCs.

Will deleting the AppData folder remove my Zoom settings and contacts?

Yes — your local Zoom settings will be reset. However, your meetings, contacts, and account data are stored in Zoom's cloud. You will not lose anything important by deleting this folder.
