Download TMST_Master.docx and convert with Aspose.Word 17.4 tool.
Same exception occurs for
LM Funding - Form 8-K - Earnings Release (Q4 and YE 2015).docx file attached.
conversion failed on doc.Save(myDir + “Out_” + docName + “.html”, SaveFormat.HtmlFixed);
Please see screenshot.
Workaround. If I go in Word [Review] -> [Changes] ->[Accept all changes], save document and try to convert. In this case document is converted.
