I'm trying to install the latest version of MySQL (5.5.13 64-bit) on Windows 7 64-bit, but when it starts to configure the security settings, it shows this error:
What can I do? Note: the port is configured on 3307.
Most probably it is because of the Windows 7 firewall. You can either turn off the firewall or add a rule that would allow MySql through the firewall.
This page explains how to open a port in your firewall.
