MySQL Notifier--High Severity Error
Posted by: Jacqy Ley

When i start up Windows, MySQL Notifier pops up and displays,

"High Severity Error"
"Object reference not set to an instance of an object."

And when i click "Show Details", it shows,

at MySQL.Utility.IniFile.HasKey(String section, String keyToFind)
at MySql.Notifier.MySQLService.GetStartupParameters()
at MySql.Notifier.MySQLService.FindMatchingWBConnections()
at MySql.Notifier.MySQLService.SetServiceParameters(Boolean doNotFetchInstanceIfOffline)
at MySql.Notifier.Machine.LoadServiceParameters(MySQLService service, ChangeType changeType)
at MySql.Notifier.Machine.ChangeService(MySQLService service, ChangeType changeType)
at MySql.Notifier.Machine.LoadServicesParameters(Boolean setupWMIEventsOnly)
at MySql.Notifier.MachinesList.LoadMachinesServices()
at MySql.Notifier.Notifier..ctor()
at MySql.Notifier.NotifierApplicationContext..ctor()
at MySql.Notifier.Program.Main(String[] args)

I followed somebody's suggestion and deleted config file in User\AppData\Oracle\ and now it shows a little different details,

at MySQL.Utility.IniFile.HasKey(String section, String keyToFind)
at MySql.Notifier.MySQLService.GetStartupParameters()
at MySql.Notifier.MySQLService.FindMatchingWBConnections()
at MySql.Notifier.MySQLService.SetServiceParameters(Boolean doNotFetchInstanceIfOffline)
at MySql.Notifier.MachinesList.AutoAddLocalServices()
at MySql.Notifier.MachinesList.InitialLoad()
at MySql.Notifier.MachinesList..ctor()
at MySql.Notifier.Notifier..ctor()
at MySql.Notifier.NotifierApplicationContext..ctor()
at MySql.Notifier.Program.Main(String[] args)

I am taking a database mgmt class for the first time in my life and i have no related knowledge of whatsoever when it comes to MySQL. What i can tell you is a detailed account of my initial installation of MySQL.

(1) I downloaded the MySQL Installer for "All Windows", which seems like MySQL Community Server in a package.
(2) It was an offline version, and i chose "Development Default" or something like that. (Don't ask me why i chose it)
(3) I guess it installed Server components, then Client components as well. (I realized this Client/Server choice after 5 reinstallations)
(4) There were some "plug-ins" that were missing, and i clicked the download button to pass through. The only plug-in i didn't complete was Visual Studio 2008/2010/2012.
(5) After Server component was installed, it did some configurations, as i could see the messages on the icons tray.
(6) After some time, i realized i didn't need Server components, so i uninstalled the whole MySQL applications and reinstalled a couple of times.
(7) Bottom line is that i deleted the folder that was separately created during my initial installation (that Server component), i uninstalled completely, checked the program folder to make sure no loose ends were left on the hard drive.

I understand nobody had this kind of error, but if you have a slightest idea of what went wrong, please give me some advice on how to fix this. I am so paranoid right now that my laptop is somehow turned into an open server, in which i have no clue how to operate. (Like having a Wi-Fi router with no password)
