Error during installation – Database initialization failed

  • A+

During the final step of the installation of MySQLServer (Apply Configurations), I get a strange error. I can't get it. Here's the Log :

What's wrong here?


Just had this same problem, i don't know what caused Database initialization failed. But the error was gone after i did a complete uninstall with 'MySQL Installer - Community', restart my pc and then tried to install mysql server.
