Microsoft made this program in 2003, but I don't think they are going to upgrade this program. Since it follows older versions of setup installer, it could make problem while installing AppLocale in Windows Vista or Windows 7. It usually makes following error message:
"There is problem with this Windows Installer package. A program required for this install to complete could not be run. blah, blah..."
It is because the older versions of setup installer didn't consider the administrator previlege which is included in Windows Vista or Windows 7 recently. So, to install AppLocale appropriately, you need the administrator previlege. You can install AppLocale with the administrator previlege, do following:
1. Run command prompt as administrator
2. Type 'msiexec /i apploc.msi'
