MySQL Installation Summary: The Start service does not respond (Win7 64-bit)

MySQL Installation Summary: The Start service did not respond (Win7 64-bit) Many people encountered problems on the internet because MySQL was installed on the machine before, and the original information may not be deleted. I don't know why MySQL is so difficult for my new machine and new system. This is my case. It will be mounted to Start service at the end of each installation. There is no way. Why does it go down to Start service, it is because the previously installed MySQL has not been deleted. You can only reinstall MySQL. To sum up the steps for deleting the original MySQL information: www.2cto.com, Step 1: Delete the information of MySQL in the registry, mainly in the following three directories: 1. HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet001 \ Services \ Eventlog \ Application \ MySQL directory deletion 2. HKEY_LOCAL_MACHINE \ SYSTEM \ ControlSet002 \ Services \ Eventlog \ Application \ MySQL directory deletion www.2cto.com 3. HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Eventlog \ Application \ MySQL directory Delete Step 2: delete MySQL information in drive C: it is in the ProgramData file. Note that this is a hidden file. Step 3: uninstall the MySQL database and delete its installation directory. Then restart the machine and install it again, it should be enough to know that MySql is not easy to install, but I don't know that it is so difficult to install. After a very bad afternoon, I finally got it done.
