If you received this error after uninstalling any application that takes over the HTML open command (including, but not limited to, Chrome & Firefox browsers) you may need to change the HTM/HTML association in the registry. Set Internet Explorer as default browser before uninstalling Chrome. If you don't want to edit the registry (or use my reg file), Alan suggests reinstalling Chrome (or the offending program). Start with Edit Registry, Part 2 if you uninstalled Chrome, Firefox, or another HTML rendering application, such as Maxthon or UltraEdit, and then received the error. (Because, honestly, who would even think that would be necessary, right?) It's most common when another application installs Chrome and sets it as the default browser, then the user uninstalls it before setting Internet Explorer or Edge as their default browser. It's due to a problem with the default browser configuration, often caused by uninstalling Chrome or Firefox while the browser is set as default.
