MSI: Error! Critical action 'Updating MySQL Server component...' failed:
Command "C:\Program Files (x86)\Parallels\Plesk\admin\bin\defpackagemng.exe" --set "--type=mysqlserver" "--default=mysql51" failed with code 1. Output: Execute mysqlmng --repair-local-service failed with error code 1: Stopping MySQL server...

The entry "collation-server = utf8_general_ci" in %plesk_dir%\Databases\MySQL\Data\my.ini is causing the above error


  1. Remove "collation-server = utf8_general_ci" directive from %plesk_dir%\Databases\MySQL\Data\my.ini

  2. Restart MySQL server and run the upgrade
