We are using Aspose.Total and to convert a .doc file to docx.However,when we try to convert the attached file to .docx we notice the following run time error :-
"System.ArgumentNullException :Key can not be null,Parameter name:Key"
when we use the following:-
asposeDoc.Save(word2007Path,SaveFormat.Docx); // Error is thrown here...
Could you please advice if there is anything wrong with the attached word file?
