Microsoft.Office.Interop.Word.Application.Documents.Open ("C: \\ doc.doc") won't open
When trying to open a document (.doc or .docx), the document instance is NULL.
Application wordApplication = new Application();
wordApplication.Visible = false;
Document wordDocument = wordApplication.Documents.Open("C:\\doc.doc");
And why is wordApplication.Documents.Count zero?
(Windows Server 2008 R2 x64, MS Office 2010 x64)

There are several suggested answers, I tried the second one and it solved my problem. But I put them all here /.
1st approach: try to create a new "Desktop" directory inside "C: \ Windows \ SysWOW64 \ config \ systemprofile \"
2nd: you have to change the id of the word component in windows\System32\comexp.msc
to be interactive user, not run user.
3rd:
0. Set the DCOM setting for "Microsoft Office Word 97 - 2003 Document"
(Open Properties> Identity Tab> Select Interactive User Secutiry Tab> Lanuch and Acctivation Permissions> AddNetwork Serivce
- Save settings
- Open your virtual directory in IIS
- Select virtual directory
- Select "Authentication".
- Change Anonymous Authentication Dialog Box
- open> click on set button> admin (any admin user is good)
