Zoom Error Code 100 — What It Means & How to Fix It

What Does This Error Mean?

Zoom Error Code 100 is a general error that appears during account setup, sign-in, or when configuring Zoom settings. It usually means Zoom encountered an unexpected problem while processing your request. Signing out and back in, or clearing Zoom's cached data, typically resolves this error.

Affected Models

Zoom on Windows 10
Zoom on Windows 11
Zoom on macOS

Common Causes

Zoom's local cache files have become corrupted and are interfering with account operations
An interrupted Zoom update left the app in an unstable state
The Zoom app version is outdated and incompatible with current server requirements
A problem with Zoom's authentication servers is causing login operations to fail temporarily
Conflicting Zoom session data from being logged in on multiple devices simultaneously

How to Fix It

Sign out of Zoom completely. Click your profile picture at the top right > Sign Out. Then sign back in with your email and password.

This refreshes your session and clears authentication data that may have become stale.
Clear Zoom's app data cache. On Windows, press Windows+R, type %appdata%\Zoom, and press Enter. Delete the 'data' folder inside.

After deleting the cache, relaunch Zoom. It will recreate the folder fresh automatically.
Update Zoom to the latest version. Click your profile picture > Check for Updates. Install any available updates.

Zoom releases frequent updates — an outdated version is a common cause of Error 100.
Restart your computer and try Zoom again.

A full restart clears background processes and temporary files that can interfere with Zoom.
If the error persists, uninstall Zoom, delete any remaining Zoom folders in AppData, then download a fresh installer from zoom.us/download.

A clean installation ensures no corrupted files from a previous install remain.

When to Call a Professional

Frequently Asked Questions

Does Error Code 100 mean my Zoom account has been suspended?

Usually not. Error Code 100 is a general technical error, not an account suspension message. If your account were suspended, you would see a specific message about your account status. Try signing in at zoom.us in a browser — if the website login works, your account is fine.

I deleted the Zoom data folder and now all my settings are gone. Is that normal?

Yes. The data folder stores your local Zoom settings, custom backgrounds, and preferences. Deleting it resets everything to default. You will need to set your preferences again — virtual backgrounds, notifications, audio settings, etc. Your meetings, contacts, and recorded meetings stored in the cloud are not affected.

Can I get Error Code 100 just from being logged in on too many devices?

Yes, in some cases. Zoom allows you to be signed in on multiple devices, but conflicting session data can sometimes cause authentication errors. Using the 'Sign Out from All Devices' option at zoom.us (in your account settings) clears all sessions and lets you start fresh.
