JpDic is a Japanese-English dictionary for quick lookup of words in both English and Japanese. It still lacks the ability to sort the definition by importance/ranking.
This version fixes the installation problem on certain system. Once installed, go to Start->All Programs->up0->jpdic to run the dictionary.
.Net Framework v1.1 (can be obtained by doing Windows Update)
MDAC 2.6 or above (free download from Microsoft.com)
While learning Japanese, I wanted a free dictionary and could not find any decent win32 version so I decided to write one. It was written in C# and the dictionary data is based on EDICT project. The EDICT format was converted into MS Access database table with UTF-8 encoding.
