This article is for students who are unable to open LockDown Browser on their computers. This issue is caused by a corrupted installation of LockDown Browser or an installation that is running in an inconsistent state. Below are several methods for resolving the issue. 

Resolution 1: Interference

Some programs may be interfering with LockDown Browser.

  1. Try closing down all of the programs on your computer (other than those used to connect to the internet) before you launch LockDown Browser.

    1. This includes programs that are executed during start-up and deemed non-essential. Wireless/network connections and/or anti-virus programs do not fall under this category; you should leave these on and running.

    2. If one of the programs happens to be Chrome Remote Desktop, this will require you to temporarily remove the extension from your browser, and uninstall the program from your computer. LockDown Browser will not launch otherwise.

  2. Try to launch LockDown Browser again. 

If you are still unable to launch LockDown Browser after closing, proceed to Resolution 2. 

Resolution 2: Clear Cache

  1. Open your internet browser.

  2. Clear the cache from your internet browser. 

    1. Step-by-step instructions for clearing the cache from different browsers can be found online on the Refresh Your Cache website. 

  3. Restart your computer. 

  4. Try to re-launch LockDown Browser again.  

If you are still unable to launch LockDown Browser after closing, proceed to Resolution 3.
