You've signed-in to our online classroom to take a course. You've launched a video, and it won't play.
There are many possibilities for why videos won't play. We've collected the most common causes with suggested solutions. In some cases, you might need to ask for assistance from your corporate IT department.
Note:
This article will address computers running Microsoft Windows.
Background
We explain the possibilities by categorizing them into 3 large buckets:
- The software being used
- The corporate enterprise IT system & configuration
- The computer being used
Your Software
- Flash player - Our videos run on Adobe's Flash Player. - ADDRESS THIS FIRST -
- The web browser
- Make sure that the latest version of your browser is installed
- Internet Explorer
- Chrome browser (by Google) - videos might be more stable on Chrome
- Ad blocking software - Try turning ad-blocking off
Your Corporate IT System
- Try this easy test
- Take our course on your home personal computer. If you're successful, it suggests that the corporate hardware/software systems are the culprit.
- White listing
- Outside entities can be blocked from a corporate system. Approved entities might appear on a company's "white list." Ask your IT department if this is the case, and how our domain and/or IP address can be added, in order for the video feed to get through.
- Virus scanning & content filtering
- Ask your IT department if outside video content is being scanned/filtered, and preventing the videos from playing.
Your Computer
- Reboot your computer
- As you are opening and closing programs, your computer may or may not relinquish system resources used by these programs which can result in quirky behavior, including locking up, because the computer is not fully utilizing all of its available resources.
- Try using another computer.
- Graphics hardware and associated display drivers
- Check if you can see an HTML5 video ( If you can’t see both the videos, there may be an issue with your device driver).
- Learn how to update your device drivers
- Try disabling hardware acceleration
