"About" believe that there are many children's shoes when installing MySQL server will encounter the installation failure, I hope at this time my article can help you.
First, turn off Windows Firewall, second, turn off the MySQL service (right-click "My Computer", click "Manage", go to "services", find "MYSQL" and close), and follow the steps below:
Step One: Open the folder where you installed "MYSQL" and delete all files.
Step Two: Open "Control Panel", go to "programs and features", find "MYSQL" program, uninstall.
Step Three:
"Win7 System" C:\Documents and Settings\All Users\Application Data\mysql Delete this folder .
"Win8 system Hidden File" C:\Program files (x86) \program Data\mysql Delete this folder.
Step four: Enter "Windows key + R" from the keyboard, enter "regedit" into the registry management, click Edit Options, go to find function, enter MySQL, click Find, find and delete the directory, loop this step until you find the registry about MySQL.
Step Five: Restart the computer!!!
Finally, I wish you successfully install successfully mysql~ (you can open Windows Firewall after installation).
