I am having problem to instal ibt verification tool for toefl test center

i am having problem to instal ibt verification tool for toefl test center when its reaching on language its giving error for chines and Japanese language I installed both language after that its still giving error for these two language

If the languages work in every other way except for the verification, the problem is with the IBT setup. The following is from:
http://apcentral.collegeboard.com/apc/public/repository/ap07_techtips_ap_ibt.pdf

8. Regional Settings/Options: iBT requires that all computers’ Regional Options/Settings and Keyboard Input Locale are configured for US English. The software checks for these settings before launching. Please ensure that Regional Options/Settings for US English are installed and that the default keyboard locale is set to US English.
9. Non-US English computer names: DO NOT use non-US English characters for computer names.

If the languages aren't working elsewhere on the machine, verify the language installation procedure:

Windows XP

Windows VISTA:

go to the site: ibt1.ets.org/ibt/info.html - scroll down and click on the link"ibt bundle installer" and install that.
