Visual Studio Add in Menu Not Showing Up

[vcstarter]

I am using the following code to add a menu to visual studio here is the complete function (see below)

it works fine; the problem is when i take it to a test station (I mean when I move the dll), when I first open visual studio it shows the menu, then when I close visual studio and open it back, the menu does not show up

if I change the code when I put the menu under the tools menu, there is not problem

is there a way to fix that. I know by default visual studio add add in command to the tools menu, there must be a way to fix that

public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
        {
            _applicationObject = (DTE2)application;
            _addInInstance = (AddIn)addInInst;
            if(connectMode == ext_ConnectMode.ext_cm_UISetup)
            {
                object []contextGUIDS = new object[] { };
                Commands2 commands = (Commands2)_applicationObject.Commands;
                string testMenuName = "Test";
 
                //Place the command on the tools menu.
                //Find the MenuBar command bar, which is the top-level command bar holding all the main menu items:
                CommandBar menuBarCommandBar = ((CommandBars)_applicationObject.CommandBars)["MenuBar"];
 
                //Find the Test command bar on the MenuBar command bar. This is the "before" parameter to add new command bar:
                CommandBarControl testControl = menuBarCommandBar.Controls[testMenuName];                                
 
                //This try/catch block can be duplicated if you wish to add multiple commands to be handled by your Add-in,
                //  just make sure you also update the QueryStatus/Exec method to include the new command names.
                try
                {

                    //If we are here, then the exception is probably because a command with that name
                    //  already exists. If so there is no need to recreate the command and we can 
                    //  safely ignore the exception.
                }
