Blizzard, a subsidiary of Activation Blizzard, is a California-based company that develops and publishes video games. The Blizzard desktop application contains many errors that prevent you from playing Blizzard published games. One of these errors is the error message “The application encountered an unexpected error. This error can occur when trying to log into the application.
Often the error message is due to improperly installed or cached files in the application. A cache is a temporary file stored on your system that contains session information that you can access. This error message is generic and can be fixed with a simple solution, which we’ll mention below. But before we get to the heart of the matter, let’s take a closer look at the causes of the error message.
What is the cause of the Blizzard error message “Application encountered an unexpected error”?
As we mentioned before, this error message appears when you open the application after booting the system. It can also appear when you are playing a game and it crashes unexpectedly. This can be caused by the following reasons:
Damaged installation of cache files: The most common error message is an outdated installation or damaged cache files stored on your computer. In this case, you need to uninstall the application and delete the files manually and then install the application.
Blizzard is not installed in the root directory: The problem can also occur if the Blizzard application is not installed in the root directory of your system. I know it sounds strange, but the problem is that you have to install the application in the root directory for it to work.
