Jesper,

  Thanks for answering and sorry it took a little while to get back
to you. My boss had to find the code.

  Here's what we're using at startup of the program. The code reads a
config file for directories it needs to work. If they're not there it
creates them. That is failing on vista ultimate unless I run as
administrator. On vista home it doesn't work even if I ran as
administrator.

Here's the code and thanks again for answering.

-----------------------------------------
   Try
           _RootGroupsFolder = AppMain.AppVar.Main.MyFolder
           Trace.WriteLineIf(AppMain.AppVar.Trace.Level.Info,
"Message.", Routine)
           If bDebugStartup Then MessageBox.Show("Message.")
           If Not System.IO.Directory.Exists(_RootGroupsFolder) Then
               Viewer_StatusChange("Creating folders...")
               System.IO.Directory.CreateDirectory(_RootGroupsFolder)

System.IO.Directory.CreateDirectory(System.IO.Path.Combine(_RootGroupsFolder,
"Folder1"))

System.IO.Directory.CreateDirectory(System.IO.Path.Combine(_RootGroupsFolder,
"Folder2"))

System.IO.Directory.CreateDirectory(System.IO.Path.Combine(_RootGroupsFolder,
"Folder3"))

System.IO.Directory.CreateDirectory(System.IO.Path.Combine(_RootGroupsFolder,
"Folder4"))
           End If
       Catch ex As Exception
           HandleStartupError(ex, String .Concat("Unable to create
group folder '", _RootGroupsFolder, "'", System.Environment.NewLine,
System.Environment.NewLine, ex.Message))
           Return
       End Try
