Hello,

I've the following two problems. I want to write an inifile to the
Windows directory. And I wanna write variables to the Registry. For
both things I get an UnauthorizedAccessException. This problem started
when I'm using Windows Vista. (Windows XP this problem never happens.)
Can somebody give a solution, how to solve this? This a part of my
source:

      static string FBestandnaam;
      ...
      public string Naam
      {
         ...
      }
      ...
      public void Reset()
       {
           if (FFullBestandnaam != null)
               Close();
           //    UnauthorizedAccessException => Here the exception
starts
           FFullBestandnaam = File.Open(Naam, FileMode.OpenOrCreate,
FileAccess.ReadWrite);
           FFullBestandnaam.Position = 0;
       }

       private static RegistryKey _Key_LocalMachine =
Registry.LocalMachine;
       private static RegistryKey _Key_Software;
       private static RegistryKey _Key_Company;
       private static RegistryKey _Key;
       private static RegistryKey _Subkey;
       ...
       static void InitRegistry()
       {
           _Key_Software =
_Key_LocalMachine.OpenSubKey(sKEY_SOFTWARE, true);
           using (RegistryKey
               //  UnauthorizedAccessException => Here the exception
starts
               tempKey =
_Key_LocalMachine.CreateSubKey(sKEY_SOFTWARE))
           {
               _Key_Software =
_Key_LocalMachine.OpenSubKey(sKEY_SOFTWARE, true);
           }

           _Key_Company = _Key_Software.OpenSubKey(sKEY_COMPANY,
true);
           using (RegistryKey
               tempKey = _Key_Software.CreateSubKey(sKEY_COMPANY))
           {
               _Key_Company = _Key_Software.OpenSubKey(sKEY_COMPANY,
true);
           }
       }

Yours sincerly, Wesley
