This is highly unlikely. spy.pl will at least output usage information. Please show us how you tried to run it. So either you cannot run Perl scripts at all, or you are not telling us exactly what you did and what you got as result.

For example, it works for me like this:

> perl -w spy.pl --all
...
++         459214    , 'Button                   ', 328230    , Rect:6
+25,465,976,772   'Energiestand'
...
++         2164734   , 'EXCEL;                   ', 2426442   , Rect:-
+1 ,69 ,168,86    ''
+++        2230202   , 'ComboBox                 ', 2164734   , Rect:-
+1 ,66 ,113,88    ''

So, it clearly has access to windows and elements within windows, like a ComboBox. Maybe you really should learn how Windows structures application windows and its contents?
