Word Add-in For MediaWiki not supported in Word 2013?

Hi. The “Microsoft Office Word Add-in For MediaWiki” does not work, nor does it even appear in Word 2013’s add-ins list. Is it not supported by Word 2013, although its docs say it works with Word 2007 and above?

How can I make Word 2013 run it?
Or is there a way I can run Word 2013 in “compatibility mode” as Word 2010 ?
Plugin’s page:

Actually got this to work in regular Word 2013 without using compatibility modes. You need to create similar registry keys in

Office 15

ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftOffice15.0WordText ConvertersOOXML ConvertersExportMediaWiki
from Office 14 keys
