Sorry for being so clueless but I also have the same problem someone a few pages back had (that was never solved).
My installation has no exe file in the folder after I run the installer. I use "run with Japanese applocale as Admin" to install (shows all the Japanese text in installation). It installs with no problems but the exe file is not there when it completes. It says it can't find the file when it tries to run the game. I tried installing it without using the applocale (shows jumbled unreadable text) and then it has errors during the install, including saying there are syntax errors with ????.exe. Which is probably the file I need. But I don't understand how to get that exe file installed. Either way I get nothing.
Anyone have any ideas? Thanks for any assistance! I've been reinstalling this game over and over for the past hour and nothing is working.. Every other Japanese visual novel / game I've installed works great with the Japanese applocale install.
