C# powerpoint edit smartart text

I am currently trying to replace some text in a powerpoint smartart object. I can get the text but I am unable to set the text value even when a lot of documents make it seem very easy.

I am using 

shp.SmartArt.AllNodes[i].TextFrame2.TextRange.Text = shapeString;

to set the text string but I am coming up with an error no matter what function I use

shp.SmartArt.AllNodes[i].TextFrame2.DeleteText();

returns the same error message as the other message. I may need to make the powerpoint visible but for some reason when I make it visible it disappears. (anti-virus?)

I can replace text in the powerpoint with standard text boxes so I am trying to repeat the steps for smartart with no success.

I don't work with Interop, but you might try testing first whether a node has text first before changing it. Some SmartArt variants have text nodes that can't be set programmatically, so trying to add text on them will always fail. This is working to set SmartArt text here, using this VBA:

If ActivePresentation.Slides(1).Shapes(1).SmartArt.AllNodes(X).TextFrame2.HasText Then
    ActivePresentation.Slides(1).Shapes(1).SmartArt.AllNodes(X).TextFrame2.TextRange.Text = "Text"
End If

I ended up using openxml to work around this issue. I am unfortunatly switching between openxml and interop until I can find a better fix.

using (PresentationDocument doc = PresentationDocument.Open(textBox1.Text, true))
{
       PresentationPart pp = doc.PresentationPart;
       SlidePart sp1 = pp.SlideParts.ToList<SlidePart>()[0];
       foreach (DiagramDataPart ddp in sp1.DiagramDataParts.ToList<DiagramDataPart>())
       {
             DataModelRoot dmr = ddp.DataModelRoot;
             List<PointList> pl = dmr.Descendants<PointList>().ToList();
             foreach (PointList item in pl)
             {
                    List<Point> ps = item.Descendants<Point>().ToList();
                    foreach (Point p in ps)
                    {
                          if (p.InnerText.Equals("_HELLO_"))
                          {
                                DocumentFormat.OpenXml.Drawing.Paragraph para = p.TextBody.GetFirstChild<DocumentFormat.OpenXml.Drawing.Paragraph>();
                                DocumentFormat.OpenXml.Drawing.Run run1 = para.GetFirstChild<DocumentFormat.OpenXml.Drawing.Run>();
                                DocumentFormat.OpenXml.Drawing.Text text1 = run1.GetFirstChild<DocumentFormat.OpenXml.Drawing.Text>();
                                text1.Text = "World";
                                var textreplacement = p.InnerText;
                          }
                    }
              }
        }
        doc.Save();
}
