I have been having this problem for about a month now, and I'm not sure why. Whenever I'm in a program and I go to the 'download update' link, or I'm in a program and I click on 'web support', or anything else that would normally launch a browser, I get a prompt to print instead. I have a default browser; it just doesn't ever launch.
Please let me know if you need any more information. Thank you.
