Adding another MySQL version is very easy and safe with Laragon.
Hint: This tutorial also applies for MariaDB.
https://downloads.mariadb.org/mariadb/10.2.6/#os_group=windows
[Download the MariaDB 64-bit version]
https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.18-winx64.zip Extract the downloaded to: {LARAGON_ROOT}\bin\mysql\mysql-5.7.18-winx64 (see below Note for MariaDB) C:\laragon -- bin -- mysql -- mysql-5.7.18-winx64 -- ............. Select the new version at: Laragon Menu > MySQL > Version > mysql-5.7.18-winx64
Very easy huh. That's all forks!
Note: If you use MariaDB, extract it to: {LARAGON_ROOT}\bin\mysql\mariadb-10.2.6-winx64, Laragon will automatically create correspond DataDir for MariaDB on data/mariadb
