16. Reference: MySql installation database initialization error . This is a bug in the 8.0.11 installer. Although the error was different, I decided to download the latest version of MySQL Installer, mysql-installer-community-8.0.39.0.msi. The installation succeeded, and no more errors were reported. As shown in Figure 16
