Error during reinstallation or update of the Block 64 Discovery Application
When attempting an update or reinstallation of the Block 64 Discovery Application, an error will sometimes be encountered that indicates MySQL could not be extracted.
This is due to an instance of MySQL not shutting down completely when attempting to modify its file structure or install a new version.
A simple resolution is to restart the host machine and re-attempt the update or reinstallation of the Block 64 Discovery Application.
If a reboot is not possible, you can navigate to services and manually stop the mysqld service that is not responding.
