GetPreviewBitmap AxHost Class not licensed

2015 SOLIDWORKS API Help - Get Preview Bitmap of Drawing Sheet Example (VB.NET)

My DocumentMgr key works for the Doc Manager, but the AxHost I am unsure of.

I am receiving an error with the AxHost in Class to get the picture.

Error: Class is not licensed for use (Exception from HRESULT: 0x80040112)

Where exactly is this license supposed to come from?

Class PictureDispConverter

     Inherits System.Windows.Forms.AxHost

     Public Sub New()

          MyBase.New("?")    

     End Sub

     Public Shared Function Convert(ByVal objIDispImage As Object) As System.Drawing.Image

          Dim objPicture As System.Drawing.Image

          CType(System.Windows.Forms.AxHost.GetPictureFromIPicture(objIDispImage), System.Drawing.Image)

          Return objPicture

     End Function
