My SQL Error 1067: The process terminated unexpectedly!

By | August 8, 2014

My SQL Error 1067If you are trying to install MySQL v5.5 on the Windows machine with Windows 7×64 Enterprise edition and it is installed fine but when you are running the “MySQL Instance Configuration Wizard” it gets paused forever. Then you will come to know that the “MySQL” service hasn’t started, and if I try to restart it, it says you “Windows could not start MySQL Service on Local Computer. Error 1067: The process terminated unexpectedly.”

This error stuck the screen for long time and it does not go until you kill the process.

 If your machine works 100% on every other way and it is 100% good in installing any other compatible databases such as InfiniDB.

You can try using MySQL v5.1 update but it does not work. The amazing part of this is that if you type “mysqld /?”, or “mysqld -help” then it will not provide you help and if you restart the service manually then it will not display any error message. So it cannot be helpful for you.

Update 2010-12-21

If you install the MySQL 6.0 alpha at this time then it will work.

In this version of MySQL you can see the same problem.

To fix all the above problems you need to:

Step 1: As by default it is important to find out the reason why the service fails to start. You need to tell the service to start in the non service mode and will pipe errors to the console.

 mysqld –console

Step 2: in some of the particular cases the deletion of the contents of:


Then you need to reinstall the MySQL v5.5 installer and if contains bug then you need to uninstall MySQL v5.5 to fix a problem with a bad installation then it fails to clean up the C:\ProgramData\MySQL which means that it becomes impossible to install the MySQL v5.5  on the machine on that moment without deleting the rogue file.


  • You need to ensure that you have killed all the instances of “mysqld” in the process monitor.
  • Then you start to remove the existing services, use “sc and delete MYSQLxx”.
