Registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Nls\Language\InstallLanguage should contain same number as registry key HKEY_CURRENT_USER\Control Panel\International\Locale to make both Autohotkey and gimp detect the language of Windows right.
What is the purpose of that check?
Under Wine this is not the case.
What exactly happens if the value of that key is english? That key has nothing to do with the user locale.
