Can't open docx file attachment in Thunderbird

I am unable to open up a Word docx file attachment in Thunderbird. I can open a Word doc file attachment, but not a docx file attachment. "Use Word (default)" are both the "Actions" that are set to open a Microsoft Word 97-2003 document and Microsoft Word Document under 'Settings/General/Files & Attachments'.

Try this: click the Action drop-down for docx files in the Files & Attachments section, Use other..., then Browse... to the Word executable, e.g. word.exe. Restart TB and see if docx attachments open. The attached picture shows the dialog with TB 102, but in TB 115 it is clipped at the bottom.
