1. 用系統管理者權限來執行命令提示字元 means you have to open Command Prompt window in Vista. See this link for how to run command prompt with Administrator mode
http://www.howtogeek.com/howto/windows-vista/run-a-command-as-administrator-from-the-windows-vista-run-box/
2. After the command prompt window (DOS) open, you have to change the folder where your Applocale setup exe file stored. For example; if you saved your Applocale setup files in your user profile, try steps below.
a. before you open dos prompt windows, write down the path of the setup files where Applocale saved.
b type "cd c:\<applocale path>"
e.g. this is just an example.
cd C:\Documents and Settings\Administrator\Desktop\applocale
(change the folder to the root of C: drive, by default once you enter DOS prompt, you will be lead to C: drive)
