This is a patch file if you have the 1.11 version of Something's In The Air Redux, the version designed for Steam, but also the current version on all other sources.

While getting ready for Steam, there is a change in the Rachel Meets Ariane "Top Club" scene that had to be replaced because it violated Steam rules. It is a scene with Ariane dressed up in a school girl outfit as part of a sexual encounter at the club. It had to be changed to a Kimono.  Personally I like the Kimono version better, but there have been requests to bring the school girl outfit back, so there is a patch to do that.

On PC or Linux, extract the file to the directory where the SomeInTheAirRedux.exe is located, say yes to replace files.

On Steam you can find this by right clicking on Something's In The Air Redux in the steam library, selecting "Manage" and then "Browse Local Files"

On Mac you control-click (right-click) the Something's In The Air Redux app, Show  Package Contents, go to Contents/Resources/autorun/ and drag the patch game folder, and if a window pops up, choose “Combine”.
