Mysql Service Help Needed

I have just installed MySQL and ran the configuration wizard. The wizard failed to start the service, and I can't start it using services.msc either, this is what comes up in the Windows Event Viewer:

Plugin 'FEDERATED' is disabled.Plugin 'InnoDB' init function returned error.
Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
Unknown/unsupported table type: INNODB
Aborting
Forcing shutdown of 1 plugins
C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld: Shutdown complete

I have tried reinstalling MySQL but it didn't help. I also tried deleting the service and recreating it via the MySQL configuration wizard but the same error occurred.

What should I do?

Which mysql distro are you using ? On which OS ?
I would recommend you to use the portable version of XAMPP, it does not need to be "installed", you find it here : http://portableapps.com/apps/development/xampp

XAMPP is an integrated server package of Apache, mySQL, PHP and Perl (the AMPP in XAMPP) that all run from a removable drive. Everything is pre-configured and ready to go just by unzipping or installing it.

I'm using MySQL 5.1 on Windows 7 RC. I can't use PortableApps if I use NetBeans. I already have Apache and PHP installed but blocked with the firewall (local access only).
