installation problem of Unitex 3.1 on Mac (10.11.6)

[kozue ogata]

Hello, I have a problem in installation (or opening) of Unitex 3.1 on IMAC (System El Capitain version 10.11.6). Unitex 3.1 is apparently installed because when I double click on the ICON Unitex (with Java version 8) it shows a message "Welcom, Your private Unitex directory where you can store is /Users/.....etc." Then it shows the message of the attached photo 0338 saying "We could not open Java JAR file "Unitex.jar" Check error message in Console." Console pictures are attached 0342 and 0344.  On the other hand, I can open Gram.jar without problem.  Would anyone know where is the problem ? Best regards, K. Ogata
