How to Fix the Blizzard Error the Application Encountered an Unexpected Error in Windows 10

Blizzard, a subsidiary of Activation Blizzard, is a Californian company that develops and publishes video games. Blizzard’s desktop application has many bugs that prevent you from playing games published by Blizzard. One of these errors is the error message “The Application Encountered an Unexpected Error”. This error may occur if you try to connect to the application.
The error message is often due to a faulty installation or application cache files. The cache is a temporary file that is stored on your system and contains information that you can access through your sessions. This error message is generic and can be solved by a simple solution, which we will mention below. But before getting to the heart of the matter, let’s take a closer look at the causes of the error message.
Performing a Clean Install of the Blizzard Application
As the issue is related to corrupted cache files or outdated installation of the application, the only way to fix the issue is to perform a clean install of the Blizzard application. This includes manually deleting the cache files and then downloading and installing the application. So, let’s begin. Here’s how to do it:
1. First of all, make sure that all the processes of the Blizzard application are closed. Open up a Task Manager, and go through the running applications to make sure Blizzard is not running (if you see a process by the name agent.exe, end it as it is associated with Blizzard).
2. Afterward, open up a Control Panel and go to the Uninstall a Program section.
3. Look for Blizzard in the list and double-click on it to uninstall the application.
4. Once done, press Windows Key + R to open up the Run dialog box.
5. Type in C:\ProgramData and press Enter.
6. A window of the File Explorer will pop up. Look for any (includes Blizzard Entertainment) folders in the directory and delete them.
7. Afterward, press Windows Key + R again to open up the Run dialog box.
8. Type in %AppData% and press Enter.
9. This will take you to the Roaming folder of the AppData directory. Search for any or blizzard folders and delete them.
10. After that, hit Backspace and go to the AppData/Local directory and do the same there as well.
11. Once done, head to the Blizzard website and download the latest version of the application. You can find it by going here.
12. Install the application. (Make sure you install it in the root directory of your system. The root directory is where Windows is installed)
13. Open up the application, and log in to your account.
14. Enjoy your gaming sessions!
