The NaCl module allows Screencastify to encode your recordings into a format you can play back in your browser, share, and export.
If you're receiving a "Failed to load NaCl module" error, please take the following steps to troubleshoot and resolve the issue:
- Restart your computer and try again
- Uninstall and reinstall Screencastify and try again (WARNING: if you save your recordings locally and not to your Google Drive, they will be permanently deleted when you uninstall Screencastify. Export them first.)
- Change Screencastify's default encoder from NaCl to WebRTC (click here for instructions)
If these steps don't work, please submit a support ticket for further assistance.
