C# connection to Autocad LT 2014

Hi all!

I have a c# connection, this code run fine in Autocad 2014. The final purpose of my program is create a .dwg file and add labels in mentioned .dwg file but not work in Autocad LT 2014 .

My code:

try
{

// Upon creation, attempt to retrieve running instance
m_AcadApp = (AcadApplication)Marshal.GetActiveObject("AutoCAD.Application.19");
m_bAcadInit = true;
}
catch
{
try
{
// Create an instance
m_AcadApp = new AcadApplication();
m_bAcadInit = true;
} catch(Exception ex)
{
MessageBox.Show("An error occurred trying to open the AutoCAD.", "Attention", MessageBoxButtons.OK, MessageBoxIcon.Information);

//In LT version this message appears

}

Is possible open Autocad LT 2014 with my code or similar code?

Thank you very much.
