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).

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 Battle.net 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)
