Chih Ho, once you are installing, have a look at /proc/cmdline as well as c:\ubuntu\install\custom-installation\preseed.cfg (that one gets deleted at the end of the installation) and the Wubi log in your %temp% directory. Check if anything is out of place wrt language set-up. There is a rev170 on the website you can try as well.
