I am using VC# 2010 to open a Word 2007/2010 document stored in my system running on windows 7 platform, the code I am using is given below:
ApplicationClass wordApp = new ApplicationClass();
Paths = Paths + "\\" + strDayofWeek;
object file = Paths;
object nullobj = System.Reflection.Missing.Value;
* Document doc = wordApp.Documents.Open(
ref file, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj, ref nullobj, ref nullobj,
ref nullobj);
The line of code with asterisks (*), generates the following error message:
System.Runtime.InteropServices.COMException was unhandled

Sorry, but strDayofWeek has no error on it, it has been declared earlier in the method and is used to read the days of the week from an array of days of the week.
Thanks.

write before calling Open on Word app following line:
MessageBox.Show(System.IO.File.Exists(file).ToString());
what does it show?

I was seeing very similar problem. I was needing to inject a wait between starting Word up and then attempting to open the document.
So... I just tried making sure I have the fully qualified path to the document that I am trying to open. When I did this all started working OK for me.
So to be clear all I did was move from code that looked like this
string filename = @"myDoc.docx"); var document = wordApp.Documents.Open(FileName: filename, ReadOnly: true);
over to something like
string filename = Path.Combine(AppDomain.CurrentDomain.BaseDirectory , @"myDoc.docx"); var document = wordApp.Documents.Open(FileName: filename, ReadOnly: true);
Hope this helps.
