C:\>tracert win7x64

Minimum …当我启动 MySQL Notifier 时，显示如下错误：
“高严重性错误”“未将对象引用设置为对象的实例。”
当我点击“ Show Details”时，我可以看到程序的异常堆栈跟踪：
在 MySQL.Utility.IniFile.HasKey(String section, String keyToFind) 在 MySql.Notifier.MySQLService.GetStartupParameters() 在 MySql.Notifier.MySQLService.FindMatchingWBConnections() 在 MySql.Notifier.MySQLService.SetServiceParameters(Boolean doNotFetchInstanceIfOffline) 在 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() 在 MySql.Notifier.NotifierApplicationContext..ctor() 在 MySql.Notifier.Program.Main(String[] args)
我该怎么做才能正确启动程序？
