Bonjour,
 
J'ai tenté d'installer Mysql sur mon windows 10 pro IIS avec Mysqlinstaller community mais j'obtiens invariablement cette erreur :

J'ai tenté MySql 8.0.20 et 5.7.30 les deux en 64bits
 
Une idée ? Car là je nage...

Je pense qu'il faut rajouter la ligne suivante dans le fichier de configuration de MySQL (my.ini ou my_source.ini) :
innodb_flush_method=normal
