How to find the Zoom app's bit version

1. On your computer, access the Task Manager application.
2. In the navigation menu, click the Processes tab.
3. Under Processes, find Zoom Meetings and view the following:
   • If the Zoom application states 32-bit next to it, then you have the 32-bit version.
   • If the Zoom application does not have anything next to it, then you have the 64-bit version.

How to fix it

Uninstall and reinstall Zoom

1. Run CleanZoom (updated November 30, 2023) to uninstall Zoom completely.
   Note: Use of the clean uninstaller will completely remove the Zoom client, as well as the Zoom plugin for Outlook. The Outlook add-in, Chrome/Firefox extensions, and Google Workspace add-on are unaffected.
2. In the download center, download and install the 64-bit Zoom client for meetings.
3. Once installed, open the Zoom desktop client, start a meeting with screen share, and test to see if the issue persists.

Update all computer drivers

Update all your drivers, including BIOS. If there is an update for your driver, update it immediately.

Modify the Video Rendering Method

If the issue persists after uninstalling and reinstalling Zoom, change the Video Rendering Method in the Zoom desktop client.

1. Ensure that you're using the 64-bit client.
2. Sign in to the Zoom desktop client.
3. Click your profile picture, then click Settings.
4. In the navigation menu, click Video .
5. Click Advanced.
6. Under Video Rendering Method, click the dropdown menu and select Direct3D9.
7. Restart your computer, then test the screen share again.
