When I save and open a DOCX file I am getting a corruption error.
If I open the document using WORD (without Aspose) the document opens fine.
I have tried using
OoxmlSaveOptions opt = newOoxmlSaveOptions(SaveFormat.Docx);
opt.Compliance = OoxmlCompliance.Ecma376_2006;
but the problem still remains.
Changing the same code to deal with a DOC file instead of DOCX works fine.
Strange thing I noticed was that if a footer is inserted into the docx file using Apose library, the document is displayed without error.
(see attachment for error dialog being displayed)
