You can modify the default installer display font when you start the InstallShield. For example:
x:\setup.exe -is:javaconsole -font "FZFangSong"
Here, x: is your CD drive. The example uses the Chinese font FZFangSong and requires that your regional options are set to a Chinese locale. To set regional options, go to the Control Panel, choose Regional and Language Options, and select the Regional Options tab.
To ensure that characters are displayed correctly, the JAVA_FONTS environment variable must point to the location of the font files. Otherwise, InstallShield terminates with this message:
Invalid command line option: unable to find fontname font. Make sure the font name is correct and JAVA_FONTS environment variable is set.
