Add in installed and referenced

I want to check if addin is installed and is referenced. The below code checks for add in is installed or not. How can i check if its referenced in excel.

By Refernced i mean is Tools > Addins > Addins Dailog box > If addins is installed > check if a addin with particular name is checked.

I would like preferably without any loop.

Sub Demo() 
    Dim b As Boolean 
    b = CheckAddin("Solver add-in") 
    MsgBox "Solver is " & IIf(b, "", "not ") & "installed" 
End Sub 

Function CheckAddin(s As String) As Boolean 
    Dim x As Variant 
    On Error Resume Next 
    x = AddIns(s).Installed 
    On Error Goto 0 
    If IsEmpty(x) Then 
        CheckAddin = False 
    Else 
        CheckAddin = True 
    End If 
End Function

I've had a problem that even when the function returns True, I would still get an error when trying to use that addin. It turns out, an addin can be installed, but not "open". So, in addition to checking for the addin, I also check if the addin file is open. If not, I open the addin. See my question and answer here:

Sub Sample()
    Dim wbAddin As Workbook

    On Error Resume Next
    Set wbAddin = Workbooks(AddIns("My Addin").Name)

    If Err.Number <> 0 Then
        On Error GoTo 0
        'Set wbAddin = Workbooks.Open(AddIns("My Addin").FullName)
        Debug.Print "Not Referenced"
    Else
        Debug.Print "Referenced"
    End If
End Sub

You need to test is the addin is open, pretty much like any other workbood. This will return True if an addin is loaded:

Function AddinIsLoaded(AddinName As String) As Boolean
On Error Resume Next
AddinIsLoaded = Len(Workbooks(AddIns(AddinName).Name).Name) > 0
End Function

For example:

Sub Test
Debug.Print AddinIsLoaded("Solver add-in")
End Sub
