My download of the trial failed midway through, and wasn’t able to complete.

This may have to do with the internet browser you're using, or your internet connection.

To troubleshoot, check if your internet connection is working normally, by visiting a website in your browser, such as Google.com.

Users on Google Chrome may additionally try following these tips from these help sites (links open in a new window):

• Google Chrome Help Forum: Chrome blocking downloads or seeing network error?
• Superuser.com: Why is my chrome failing to download some files?

If the issue persists, give it a short wait and try again after a few moments.
