What does the "Invalid configuration file" error mean when using MapViewer's Check for Update command?

The "Invalid configuration file" error when running the File | Online | Check for Update command is most likely caused by the application having problems contacting our update server due to a company firewall or proxy server.


If it is a proxy server issue and you have the proxy server information, go to File | Online | Check for Update, and in the Internet Update dialog, click the Advanced button. Toggle Specify proxy server information, enter the proxy server information, and click OK and Next to continue.


If you don't have the proxy server information, or it is a company firewall that is causing this and you don't have permission to disable the firewall or turn down the settings, you can download the full updated version from our MyAccount portal by following the instruction in this article.
