File permission (write)

Hello,
Once I got this code to work with out any erros, and it downloaded the file.
Now it gives me a permission error,
I don't get the acesscontrol pop up that window should show.
Anyways,
How can I get this code to download my file?

WebClient request = new WebClient();
request.Credentials = new NetworkCredential(txtFTPuser.Text, txtFTPpassword.Text);
byte[] fileData = request.DownloadData(fullDownloaPath);//dnoces.dreamhost.com
FileSecurity security = File.GetAccessControl(downloadTo);

FileSystemAccessRule rule = new FileSystemAccessRule(@"BUILTIN\Users", 
    FileSystemRights.FullControl, AccessControlType.Allow);

File.SetAccessControl(downloadTo, security);
try
{
    FileStream f = File.Create(downloadTo/*+@"\"+file*/);
    f.Write(fileData, 0, fileData.Length);
    f.Close();
    MessageBox.Show("Completed!");
}
catch(Exception e)
{
    MessageBox.Show(e.Message);
}

What is in the 'downloadTo' variable ? I'm a little confused by your code. Since you can perform a GetAccessControl() I assume it must contain your Folder. If it would be your file, it would fail because it doesn't exist yet.

but then your code continues with 

FileStream f = File.Create(downloadTo/*+@"\"+file*/);

since you wrote the /* */ your 'file' variable is commented, which makes me assume downloadTo than must contain the full path including the filename.

can you try and hardcode your destination file ?

(e.g. FileStream f = File.Create(@"c:\\users\\your user\\myfile.bin");

As far as I can interpret your code you're trying to write to Folder as such without specifying a filename.
