Hi,

I got problem when create an instance/object CAcroPDDoc in User laptop for second PDF.
But it can run successfully in my laptop.

The following is my code:

private void PrintPDF(string pFileName)
{
   bool BOpenDoc = false;

   //Create an Acrobat AV Document object
   Type TypeAcrobatAVDoc;
   TypeAcrobatAVDoc = Type.GetTypeFromProgID("AcroExch.AVDoc");
   Acrobat.CAcroAVDoc ObjAdobeAVDoc = (Acrobat.CAcroAVDoc)Activator.CreateInstance(TypeAcrobatAVDoc);
   BOpenDoc = ObjAdobeAVDoc.Open(pFileName, "");

   if (BOpenDoc)
   {
      //Create an Acrobat Document object
      Type TypeAcrobatPDDoc;
      TypeAcrobatPDDoc = Type.GetTypeFromProgID("AcroExch.PDDoc");
      Acrobat.CAcroPDDoc ObjAdobePDDoc = (Acrobat.CAcroPDDoc)Activator.CreateInstance(TypeAcrobatPDDoc);
      ObjAdobePDDoc = ObjAdobeAVDoc.GetPDDoc();

      int IntStartLine = 0;
      int IntEndLine = ObjAdobePDDoc.GetNumPages() - 1;

      ObjAdobeAVDoc.PrintPagesSilent(IntStartLine, IntEndLine, 3, 1, 1);
      ObjAdobePDDoc.Close();
   }
   ObjAdobeAVDoc.Close(Convert.ToInt32(true));
}


private void Button_Click(object sender, EventArgs e)
{
   string strFile1 = "File1.pdf";
   string strFile2 = "File2.pdf";
   PrintPDF(strFile1);
   PrintPDF(strFile2); //Got error
}

Then I got error in below code:

Acrobat.CAcroAVDoc ObjAdobeAVDoc = (Acrobat.CAcroAVDoc)Activator.CreateInstance(TypeAcrobatAVDoc);

Below is the error message:
Creating an instance of the COM component with CLSID {72498821-3203-101B-B02E-04021C009402} from the IClassFactory failed due to the following error: 80010108 The object invoked has disconnected from its clients. (Exception from HRESULT: 0x80010108 (RPC_E_DISCONNECTED)).


User uses Acrobat XI and physical printer.
I use Acrobat Pro DC and Virtual printer.
I don't know exactly what went wrong.

Anyone can help me please?
Thank you.

What I have tried:

I already used many virtual printer like "Microsoft Print to PDF", "One Note", "Microsoft XPS Document Writer".
But no error.
