通过链接启动应用程序时出现System.UnauthorizedAccessException

Question

i've been wrote an application (C#, VS2013), and add installation to it (flexera). Installation process provide copy files to ProgramFiles direcotiry and create a shortcut(link) on desktop. So, when i click on shortcut - program doesn't start, and in windows event log i see those exceptions:

Сведения об исключении: System.UnauthorizedAccessException Стек: в System.IO.__Error.WinIOError(Int32, System.String) в System.IO.Directory.InternalCreateDirectory(System.String, System.String, System.Object, Boolean) в System.IO.Directory.InternalCreateDirectoryHelper(System.String, Boolean) в main_windows.Settings.Log(System.String) в main_windows.Settings..ctor() в main_windows.Program.Main()

if i start shortcut as administrator - everything fine.

at that time, if i go to folder with installed program and click on exe-file - it starts and there is not need to start it as admin.

I try different ways to solve this, by changing permissions to folder and file, including switch off/on inheritance, but unsusccessfull...

Question - What can i do, to solve my problem.

namespace main_windows
{

    static class Program
    {
        [DllImport("user32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool SetForegroundWindow(IntPtr hWnd);
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            bool createdNew = true;
            using (Mutex mutex = new Mutex(true, "Settings", out createdNew))
            {
                if (createdNew)
                {
                    Application.EnableVisualStyles();
                    Application.SetCompatibleTextRenderingDefault(false);
                    Application.Run(new Settings());
                }
                else
                {
                    Process current = Process.GetCurrentProcess();
                    foreach (Process process in Process.GetProcessesByName(current.ProcessName))
                    {
                        if (process.Id != current.Id)
                        {
                            SetForegroundWindow(process.MainWindowHandle);
                            break;
                        }
                    }


                }
            }
        }
    }

private void Log(string s)
{

    string file = Application.ExecutablePath.Substring(0, Application.ExecutablePath.LastIndexOf('\\'));
    file += "\\logs\\";
    if (!Directory.Exists(file))
        Directory.CreateDirectory(file);
    file += DateTime.Now.Date.Year.ToString();
    file += "-" + DateTime.Now.Date.Month.ToString();
    file += "-" + DateTime.Now.Date.Day.ToString();
    file += (".log");
    FileStream fs = new FileStream(file, FileMode.Append);
    StreamWriter sw = new StreamWriter(fs);

    sw.WriteLine(DateTime.Now.Hour.ToString("00")+ ":" +
                 DateTime.Now.Minute.ToString("00") + ":" +
                 DateTime.Now.Second.ToString("00") + " " + s);
    sw.Close();
    fs.Close();
