Question

i am trying to get my application to be allowed through firewall, as I have to do ftp in active and passive mode is not an option as servers are not configured for that. so i tried the below code which compiles fine, I exexcute it using:

 MyApp.Classes.INetFwMgr mgr = new MyApp.Classes.INetFwMgr();
    mgr.AuthorizeApplication(Application.ProductName, Application.StartupPath,
        NET_FW_SCOPE_.NET_FW_SCOPE_ALL,
        NET_FW_IP_VERSION_.NET_FW_IP_VERSION_ANY);

And the class which does the job:

private const string CLSID_FIREWALL_MANAGER = 
"{304CE942-6E39-40D8-943A-B913C40C9CD4}"; 
private static NetFwTypeLib.INetFwMgr GetFirewallManager() 
{ 
Type objectType = Type.GetTypeFromCLSID( 
new Guid(CLSID_FIREWALL_MANAGER)); 
return Activator.CreateInstance(objectType) 
as NetFwTypeLib.INetFwMgr; 
} 


private const string PROGID_AUTHORIZED_APPLICATION = 
"HNetCfg.FwAuthorizedApplication"; 
public bool AuthorizeApplication(string title, string applicationPath, 
NET_FW_SCOPE_ scope, NET_FW_IP_VERSION_ ipVersion) 
{ 
// Create the type from prog id 
Type type = Type.GetTypeFromProgID(PROGID_AUTHORIZED_APPLICATION); 
INetFwAuthorizedApplication auth = Activator.CreateInstance(type) 
as INetFwAuthorizedApplication; 
auth.Name = title; 
auth.ProcessImageFileName = applicationPath; //Getting Access Denied Exception Here
auth.Scope = scope; 
auth.IpVersion = ipVersion; 
auth.Enabled = true; 
NetFwTypeLib.INetFwMgr manager = GetFirewallManager(); 
try 
{ 
manager.LocalPolicy.CurrentProfile.AuthorizedApplications.Add(auth); 
} 
catch (Exception ex) 
{ 
return false; 
} 
return true; 
}

using above code, but i get Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)) c# exception on line

auth.ProcessImageFileName = applicationPath;

any ideas what to do ?

Edit1: How would i run this as an admin using code?

Edit2: I also tried Putting <requestedExecutionLevel level="requireAdministrator" uiAccess="false" /> in manifest did not make a difference

P.S.This programs execution context can be Win 7, vista, xp

i have observed that if i change the order of ftp download statements to following windows dialog appears asking that do you want to allow this program access through firewall; if i click allow access the code works perfectly.

requestDownload = (FtpWebRequest)WebRequest.Create(uri);
                            requestDownload.UsePassive = false;
                            requestDownload.KeepAlive = false;
                            requestDownload.UseBinary = true;
                            requestDownload.Method = WebRequestMethods.Ftp.DownloadFile;


                            requestDownload.Credentials = new NetworkCredential(ftpInfoDownload[3], ftpInfoDownload[4]);

                            responseDownload = (FtpWebResponse)requestDownload.GetResponse();
                            Stream ftpStream = responseDownload.GetResponseStream();
