The MySQL 9.1 installation fails due to an Access Violation error (0xC0000005), likely caused by missing dependencies, incorrect permissions, or a bug. To fix it, run MySQL Installer as Administrator, ensure VC++ Redistributables (2015-2022) are installed, and temporarily disable antivirus/Windows Defender. Try manually initializing MySQL via Command Prompt:


"C:\Program Files\MySQL\MySQL Server 9.1\bin\mysqld.exe" --defaults-file="C:\ProgramData\MySQL\MySQL Server 9.1\my.ini" --initialize-insecure


Also, check Windows Event Viewer and MySQL logs for errors. If issues persist, try MySQL 8.3 instead.
