Interop.Word Documents.Open is null

If you are still looking for the answer I have found it just a moment ago for my project.

Open DCOM Config Settings:

  1. Start -> dcomcnfg.exe
  2. Computer
  3. Local Computer
  4. Config DCOM
  5. Search for Microsoft Word 97-2003 Documents -> Properties

Tab Identity, change from Launching User to Interactive User
