In a *.vbs file detrimine the special folder for 'Program files'

I found some code for this but 'Private Declare Function SHGetSpecialFolderLocation Lib "shell32"'  generates an error.  I don't use visual basic script files that often, and cannot seem to declear much of anything like 'Dim Apple as String', however Dim Apple works.  Below is the code.  There is alot of extra special folder, but
