What can I do if an online course will not launch?

There are many web browser settings that can affect how courses launch. Here are some steps you can take to ensure your experience is not interrupted:

 Step 1: Verify that your "pop-up blocker" is not blocking the course.

Step 2: Verify that your "Adobe Flash" and "Java Script" are enabled.

Google Chrome:

While the course is launched in Google Chrome, click on the "Secure" button to the left of the Web address box. Once this is selected verify that "JavaScript" and "Flash" are marked as "allowed", then clear your web browser's cache and cookie data prior to re-launching.
