Attachments Don't Open in Internet Explorer 11

You may find that Articulate Presenter attachments don't open when your published course is viewed in Internet Explorer 11.

This is a known issue. We're investigating it now, and we'll post additional information here as it becomes available. In the meantime, add your course to the Compatibility View Settings in Internet Explorer to avoid this behavior. Here's how:

1. Go to the Tools menu, and click Compatibility View Settings. (If the Tools menu isn't visible, press the Alt key on your keyboard to reveal it.)
2. Enter the URL for your course in the Add this website field, and click Add.
3. Click Close to save the change.

If Compatibility View Settings need to be updated for a large audience, network administrators can control them through Group Policy.

Note: Previous versions of Internet Explorer and other browsers, such as Google Chrome and Firefox, don't have this issue.
