There are 2 known issues with the Anime Expo 2014 disc version of Hangeki.
1) DirectX must be installed. Even if you have DirectX installed, you may be missing some components. To get DirectX or to get any missing components, go to: http://www.microsoft.com/en-us/download/details.aspx?id=35
2) Computer user names must not have a space. “John Smith” is ok, but “John Smith” is not. If this is the problem, you will get an error saying the game file could not be found. To fix this, you can either use an account with a different name or try running the game directly from the install. To do the latter, navigate the the program folder where Hangeki is installed in the C: drive. Go Hangeki > HangekiGame. Then copy and paste HangekiArchive.exe to another folder. Run HangekiArchive.exe to extract the game. Then run Hangeki.exe to run the game.
