Getting an error in MySQL Workbench: Cannot Open Administrator I'm using local installation of MySQL CE on Windows 7 64-bit.  Tried to use Administrator part for the first time.



Here's the error I'm getting:



I also see the following in the log:

&lt;object db.mgmt.Connection&gt; key=connection could not be resolved


This information is probably not enough to diagnose the problem.  Please let me know what I need to post so I can get some help.
You are using an old MySQL Workbench version. Please update to the latest version: http://mysqlworkbench.org/2014/04/whats-new-in-mysql-workbench-6-1/.

In older versions of MySQL Workbench we had connections and management instances separated. So it could happen that you have a server instance without a connection assigned. You could edit that instance to re-assign a connection to make it work.

Since version 6.0 this separation is gone. You only have a connection with all the necessary settings for management too.
