First of all, make sure you have followed ALL of the install instructions included with your game and/or translation patch.
- Check to make sure your system locale is set to Japanese Locale for non-unicode programs (Found under the Advanced tab in Region & Language in the Control Panel).
- In addition to setting the system locale, you may need to re-install the game entirely, if you originally installed the game under default system locale.
- Using applocale may be causing unavoidable errors in running the Visual Novel.
- Older games may require running the executable in an administrative or compatibility mode.
- There may be issues with User Rights Management in Windows 7 involving games installed in the default program files folder. Try installing the game outside of C:/Program Files (x86).
- Some games may have issues with fonts or font support. Ensure you have eastern asian language packs installed. But there also may be additional custom fonts included with a patch by the translation team that need to be installed seperately.
- If a game has issues with video playback it may be because of the default settings of video codecs such as fddshow or LAV splitter. Try installing or re-installing CCCP or disabling options relating to MPEG playback.
- You may need to install/reinstall/update video card drivers and/or Direct X.
