I'm trying to write log file once application(winform) start and some oprations going on at background.

It's working fine with Visual Studio, but once I create exe file and run it... it gives an error of attempted to perform an unauthorized operation c# winform log file

Is there any other way arround to give access of instattion folder once application installed to the user's machine?

Here is my code:

public SplashScreen()

private void GrantAccess()
        var path = Path.GetDirectoryName(Application.StartupPath);

        DirectoryInfo dInfo = new DirectoryInfo(path);
        DirectorySecurity dSecurity = dInfo.GetAccessControl();
        dSecurity.AddAccessRule(new FileSystemAccessRule(new SecurityIdentifier(WellKnownSidType.WorldSid, null), FileSystemRights.FullControl, InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit, PropagationFlags.NoPropagateInherit, AccessControlType.Allow));
    catch (Exception ex)
