Our patent bar requires the freely available Java plugin from Oracle. Please ensure you are running the latest version by visiting this page.
After installing any updates offered on that site - please restart and attempt to launch the practice test again.
If that fails to resolve any issues launching our tests - your problem likely stems from some sort of configuration issue in your Internet Explorer browser. The easiest fix for that type of problem is to simply install the freely available Chrome browser from Google by visiting this page.
After you install Chrome, open our patent bar launch page in Chrome by visiting this link and then launch any of the available practice tests - good luck with your preparations!
