Prashanth,
Set the env variable as PRO_LANG=CHT for traditional Chinese, and PRO_LANG=CHS for simplified Chinese.
You should set the following config.pro options to "Yes" for Chinese GUI.
dialog_translation
help_translation
menu_translation
msg_translation
If you just need the Chinese font support, these options are set "NO". Then you will have English GUI but you can still enter Chinese.
Check your Proe license too, I know the foundation ADV does not include the Chinese language support, you need to have "CHINESE_TRANSLATION" license Extension.
Traditional Chinese is not compatible with Simplified Chinese in Proe, and vica versa. When you read the drawing containing Simplifed Chinese, but you set PRO_LANG=CHT, the text is either random ASCII or random Chinese characters.
