I'm facing a problem regarding Word interop library. I have an installation of a C# .NET 3.5 Web Service that opens an docx document. The same code unchanged was working until something changed (I don't have any idea what changed).
Now the Web Service stops (no log, no error message) when tries to create a Word.Application object.
var wordApp = new Word.Application();
I have tried also Word.ApplicationClass(), same result. I'm using the version 14 - Office 2010 which is installed on the Windows 2003 Web Server. I have also installed the PIA redistributable for Office 2010. I have removed the and add again the Word COM reference, rebuild etc.
Do you have any idea how can I find what is missing? I've done lot of googling so I'm really sorry if this question is duplicated.
