File System Object

Again, i have been having problems using the File System Object, i have been told i need to add refernece to it, if so what file do i add reference to ? If not then what do i have to do to get it working.

If i use:

Dim FSys

Set FSys = CreateObject("Scripting.FileSystem")

Or whatever it is i cannot then use:

Dim MainFolder As Folder

Because the class 'Folder' does not exist.

How do i get it working ?

It is Microsoft Scripting Runtime - file name: scrrun.dll.

Thanks Very Much.
