The message is quite clear, something is missing or invalid. What that something may be is anyone's guess.

Solution 1

Start by looking at your data file: is it a Word document at all? Is it a version of Word that the WordprocessingDocument class understands? Or is it a pre-XML format (which were generally binary rather than "human readable"?

I'd guess that you'll find an older binary format in there, in which case you'll probably need Word interop to read it.

My requirement it that i should not use interop, which needs MS office to be installed. So when i try some opensource. i found OpenXML.
