mysqlcommunityserver plugin problem

I have previously declared a property called DBTools as mysqlcommunityserver.

when I want to create an instance on line

DBTools = New MySqlCommunityServer

marks the following compile error: “Can not find a type With This name”

In other versions did not mark the error

What I can do

Thank You

does not want to recognize plugins valentina reports and ChartDirector

This is the image showing the error displayed

that would lead me to suspect the plugin is not installed
