Spectrum 10.3 Installation get failed at post installation task on Windows server with **Error during net start mysql
Please refer below screenshot -
Release : 10.3
Component : Spectrum Core / SpectroSERVER
The Spectrum Install Owner contains special characters and in this case the special character was in the beginning of the install owner user name.
$p3ctrum_svc
This caused the post installation scripts to fail at the ddm.log.
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'CREATE'@'localhost' (using password: NO)'
Change the install owner to a different name that does not contain special characters.
Do an uninstall, reboot and then another clean install and it should be successful.
If the Spectrum install user has more then 16 characters please see this KB article:
