Question

I have a C# Application that I’ve wrote. Everything works 100% besides one method. If UAC is turned on I can not save a file, not even the Settings.config. I tried using a manifest file, with no luck. What am I doing wrong?

public static void UpdateVersionText()
 {
     var wc = new WebClient();
     var utf8 = new UTF8Encoding();
     var list = utf8.GetString(wc.DownloadData("https://www.agentsarea.co.uk/photolibrary/photos/data/version.txt"));
     wc.Dispose();
     Properties.Settings.Default.version = list.Trim();
     Properties.Settings.Default.Save();
 }

Save the file to a better place. You are probably saving to the current directory, which is in /Program files/, which a normal user should not write to. Try saving to %appdata% (each Windows user has their own directory) or to %allusersprofile% (all users share the same directory).

You get either path by calling the following:

AppData for the current user:

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

All users profile directory:

Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData)
