In version 126.96.36.199 this file didn't occur a problem, in our current version 188.8.131.52 there is a problem that the pagecount can't be retrieved and the file can't be saved as pdf.
I've also tried it on the latest downloadable version.
Could you please tell us what is wrong with this specific file?
string lsFileName = @"d:\temp\669906.docx";
Aspose.Words.License loLic = new Aspose.Words.License();
Aspose.Words.Document loWord = new Aspose.Words.Document(lsFileName);
