This code seems to work regardless of the version of Acrobat.

>>Danny, Try this...
>
>FileName = Session["pdffile"].ToString(); // Set pdffile previously
>Attach = "filename="+FileName.ToString();
>Dest = @"c:\mylocation\"+FileName.ToString();
>
>FileInfo PDFFile = new FileInfo(Dest.ToString());
>
>Response.Clear();
>Response.AddHeader("Content-Disposition", "attachment; "+Attach.ToString());
>Response.ContentType = "application/octet-stream";
>Response.AddHeader("Content-Length", PDFFile.Length.ToString());
>Response.WriteFile(PDFFile.FullName);
>Response.End();
>
>With Acrobat Reader 6.0 I am able to Save and Open a PDF this way.
