Since changing the locale normally requires a restart of Windows, AppLocale is especially popular with western users of Asian applications.
The program installs itself in a subfolder of the Windows directory called "AppPatch", and when launched prompts the user for an executable to run and the desired codepage.
AppLocale is not included in normal retail versions of Windows, but is available for free download from Microsoft's website.
Running AppLocale on Windows Vista or Windows 7 is not officially supported and it fails to install on default configurations of these OS if attempted; however there is a workaround to install it (which requires starting apploc.msi file from command prompt under administrative privileges).
Unofficial solutions of this problems include a modified version of the program, called pAppLocale provided by Hung-Te Lin (林弘德 piaip) for free,[2][3] or blanking the AppLoc.tmp file, then setting it to read only.
