How to install De'Arnise Romance for BG2EE

I recently downloaded the De'Arnise Romance (the JCompton one) after hearing a lot of good things about it and I'm wondering how to install it in Baldur's Gate 2 Enhanced Edition. It's on the list for compatible mods and it has no problems installing for the original, 14 year old BG2 yet whenever I try to install it for BG2 EE the setup has a message saying ''Please run this program in your Infinity Engine game directory'' and ''FATAL ERROR: Failure(''Not a game directory)'' so I'm a bit confused.

Help would be appreciated.
