If you block access to your camera or microphone when opening Express Capture, the recorder can’t start. This article explains how to update your browser permissions and restore access.
Allow camera and microphone access
The first time you open Express Capture, your browser asks for permission to use your camera and microphone. Click Allow.
Example of the camera and microphone permission prompt in Chrome
If you select Block or Never Allow, or block access by mistake, Express Capture displays the following message:
Failed to allocate resource. Permission denied. Reset app.

Express Capture can’t access your camera or microphone until you update the browser permissions.
Re-enable camera and microphone access
-
Click the site information or permissions icon next to the website address in your browser. In some browser versions, this appears as a lock icon.

-
Set Camera and Microphone to Allow, or turn on both permissions.

-
Click Reset App on the Express Capture page.

Express Capture should now be able to access your camera and microphone. If it doesn’t reload automatically, refresh the page.
If you still can’t access your camera or microphone
- Make sure you’re using a supported desktop browser. Express Capture is not supported on mobile devices or tablets, including iPhones and iPads.
- Check that camera and microphone access is allowed in both your browser and operating-system settings. For instructions, see Enable your webcam and microphone.
- Close other applications or browser tabs that may be using your camera or microphone.
- Close and reopen your browser.
- Try another supported desktop browser.
If a Failed to allocate resource alert continues to display, see Troubleshooting “Failed to allocate resource” alerts.
