Fail configuration of MySQL server installation

Question

I was trying to reinstall MySQLServer on my local machine (Win7 32), using Windows (x86, 32-bit), MSI Installer.

When wizard configure server, after installation, gives the error "Configuration failed", with details:

mysql-server-5.5-win32:6 - Looking for valid template
mysql-server-5.5-win32:13 - Found valid template.
mysql-server-5.5-win32:20 - Attempting to process template.
mysql-server-5.5-win32:26 - Processed template.
mysql-server-5.5-win32:33 - Attempting to configure service.
mysql-server-5.5-win32:40 - Configured service.
mysql-server-5.5-win32:46 - Attempting to start service.
mysql-server-5.5-win32:100 - Unable to configure service.
mysql-server-5.5-win32:100 - Product configuration controller finished configuration.

Why does it happen?

Can it result from using a wrong "old" password that I put in the installation wizard, to set a new password? If yes - How can I clean up ALL previous settings of MySQL server?

Answer 1

Uninstall MySql and all his components excepted Oracle installer, re launch installer, do normally, when your error comes, finish the procedure of installation.

Next step, in start menu search "services", execute services administration tool, right click on the service "MySql Server XX", select "Connexion" tab and check "system account" on start user, launch the process and it would work.
