Exe can't write in a XML file in the installation folder

First of all I have to precise that I am Web developer. But face to a problem I was obliged to create an exe in WPF as simple it can sound with small datas stored in a XML file. The problem came after installation. I followed the rules but my WPF can't write in the XML file. I see that is permission because when I put all the folder installation in let's say D drive. I don't have any problem writing in the XML file. So How can I write in the XML file after installation in any client machine? Have I to add some instructions?

Since Windows 7, the default user has no administrative rights. So applications are not allowed to write in programs directory (c:\Programs\myApp), cause they are executed with user rights as default. Application data should be stored in users directory (e.g. c:\user\fred\AppData\Local).

You can get the directory easy be using the Environment.SpecialFolder-Enumeration:

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);

You can't save to Program Files on windows 7+. Instead you can create a folder in the AppData area. I use this to get an application directory 

public static string GetAppDataDir(string company, string appName)
{
   string appDataDir = Environment.ExpandEnvironmentVariables( "%APPDATA%" );
   string appDir = Path.Combine( appDataDir, company );
   appDir = Path.Combine( appDir, appName );

   if (!Directory.Exists(appDir))
      Directory.Create(appDir);
   return appDir;
}
