What is zoomopener.exe?
zoomopener.exe is a small helper utility associated with the Zoom client that processes Zoom-specific URL schemes (like zoommtg://) and meeting invite links. It coordinates with the main Zoom launcher to start or join meetings and pass meeting data securely.
Technically, zoomopener.exe registers as the URL protocol handler for Zoom links and delegates launches to zoom.exe or the web client depending on user preference. It operates as a lightweight process that runs only when a Zoom link is opened or a meeting is joined.
Quick Fact: Zoom introduced protocol handlers early to ensure seamless joining from emails and calendars.
Types of Zoom Opener Processes
- Opener Process: Handles incoming zoommtg:// and meeting invite links
- Launcher Delegate: Launches zoom.exe or web client with meeting data
- Background Monitor: Monitors protocol requests when Zoom is installed
Is zoomopener.exe Safe?
Yes, zoomopener.exe is safe when it's the legitimate file from Zoom downloaded from official sources (zoom.us or pre-installed by manufacturer).
Is zoomopener.exe a Virus or Malware?
The real zoomopener.exe is NOT a virus. Malware can masquerade with similar names, so verify the path and signature.
How to Tell if zoomopener.exe is Legitimate or Malware
- File Location: Must be in
C:\Program Files\ZoomOpener\zoomopener.exe or C:\Program Files (x86)\ZoomOpener\zoomopener.exe. Any other path is suspicious.
- Digital Signature: Right-click zoomopener.exe → Properties → Digital Signatures. Should show "Zoom Video Communications, Inc.".
- Resource Usage: Normal usage is 1-15% CPU and 50-180 MB memory. Constant high usage when idle is suspicious.

zoomopener.exe runs when you open Zoom links, join meetings from calendars, or when Zoom is configured to handle protocols automatically.

- Calendar/Email Integration: Email clients and calendars prompt Zoom to prepare for meetings via the opener.
- URL Protocol Association: Windows associates the zoommtg protocol with zoomopener.exe, enabling direct launches from browsers.
- Background Startup: If Zoom is set to run at startup, zoomopener.exe may initialize to handle links promptly.
- Software Updates: During Zoom updates, the opener may briefly start to ensure new meeting data handlers are active.
