The code is the following:

/// <summary>
    /// The Ini Files are named using AppInfo.IniName (or AppInfo.ModuleName if the IniName isn't set)
    /// </summary>
    public class LocalIni : IniFile
    {
        public LocalIni()
            : base(System.IO.Path.Combine(Directory.GetLocalDirectory(true), AppInfo.IniName + @".ini"))
        {
            //local path (ProgramData)
        }
    }

where GetLocalDirectory method is this:

 static public string GetLocalDirectory(bool bCheck = false)
        {
            SystemIni iniS = new SystemIni();
            string sLocalDir = iniS.GetString("Data", "ProgramDataPath", "");
            //do check for %PROGRAMDATA%... 
            sLocalDir = sLocalDir.Replace("%PROGRAMDATA%", System.Environment.GetEnvironmentVariable("programdata"));
            if (sLocalDir.Length == 0)
            {
                //assume it's programdata...
                sLocalDir = System.Environment.GetEnvironmentVariable("programdata") + @"\Siriusware\" + AppInfo.DirectoryName;
            }
            if (bCheck)
                CheckDirectory(ref sLocalDir);
            return sLocalDir;
        }

Right now I'm just testing from the program (.prg) in VFP, so perhaps the ini file needs to be c:\program data\siriusware\Visual FoxPro\Visual FoxPro.ini

But I'm going to try Paul's method to be sure.
