FAQ

Can I use Zoom Web Client instead of installing the app?

Yes, you can join meetings at zoom.us/join using just your browser. However, some features like virtual backgrounds and breakout rooms may be limited in the web version.

Does error 10004 mean my Zoom account has problems?

No, error 10004 is an installation error, not an account issue. Your Zoom account and meetings are unaffected. The problem is with the local installation on your computer.

Why does Zoom error 10004 happen after Windows updates?

Windows updates can change security settings or reset firewall rules. After major updates, you may need to reinstall Zoom or reconfigure firewall permissions.

Should I use the 32-bit or 64-bit Zoom installer?

Use the 64-bit version if you are running 64-bit Windows (most modern systems). Check by going to Settings then System then About and looking at System type. The 64-bit version offers better performance.
