Safe Exam Browser (SEB) Troubleshooting Guide
If a student is experiencing issues launching SEB, try the following steps. This quick fix resolves most problems.
Steps to Resolve SEB Launch Issues
- Close all browsers (Chrome, Edge, Firefox, etc.)
- Navigate to the following folder:
C:\Users\[username]\AppData\Local
(Replace [username] with the account name currently logged into the device)
- Delete the folder named
SafeExamBrowser
- Reboot the computer
- Relaunch browser → Moodle → SEB
Why This Happens
SEB sometimes doesn’t close properly and leaves behind locked session files. Deleting the folder clears these out and allows SEB to launch correctly.
Additional Notes
- If you can't find the AppData folder, it's likely hidden.
In File Explorer, click View and check Hidden items.
- The account folder name may vary on personal devices (e.g.,
Default, HP, or a nickname).
- To determine the account name, click the Start menu — it will be listed at the top.
