Thread:Extension talk:Gadgets/Activating Gadgets on 1.17?

Hi. We're running MW 1.17 and I'm trying to activate the Gadgets extension. The version linked to on the download page says that the extension requires 1.17, yet when I try to activate it I get an error message saying 1.19 or later is required. When I follow the link for older versions here: https://www.mediawiki.org/wiki/Special:ExtensionDistributor/Gadgets I see only options to download for 1.19 and 1.20. Can anyone tell me how to enable Gadgets on 1.17, if that's at all possible? thanks
