I asked /tkki/ but reply is taking longer than I hoped.
I keep getting this message http://uboachan.net/tkki/src/1366649696378.png whenever I try to install it. The wiki says this might have something to do with applocale, problem is that this isn't my first doujin game and my computer's system locale has been set to Japanese months ago.
The installation page says that I might have problems with downloading the wav files, but before that one the wav files downloaded fine.
