Solution to MySQL 5.5.29 installation failure under win7

This article introduces how to solve MySQL 5.5.29 installation failure in win7. I hope this method will be helpful to you.

I downloaded the latest version of mysql today and encountered Last error: unable to configure service during installation. An error occurred during the final configuration.

It is the same for several times. Port 3306 is definitely not occupied, and the system has never installed mysql, which is very strange.

The final solution is to change the installation directory. I installed it in D:/soft/db and changed it to D:/db. Is it related to/s ???

The following steps are successfully installed.

1. First, uninstall a series of MYSQL

2. clear the registry, Run regedit under cmd, and then-F3-search for your installation path. my options are: D:/soft/db. delete all keys or values that can be found. (quite a few)

3. Use netstat-na to ensure that port 3306 is not occupied. You can change the port to another one. My port 3306 is useless.

4. Change the installation directory to D:/db.
