How can I read the default language of installed MS Office application?

Answer:

you may initialize Word.Application instance and read a CountryID: 

1   var
2     word: Variant;
3   begin
4     word := CreateOLEObject('Word.Application');
5     CountryID := word.System.Country;
6     word.Quit;
7     word := UnAssigned;
8   end;
9   
10  After that check this CountryID with next values: 
11  
12  wdUS = $00000001;
13  wdCanada = $00000002;
14  wdLatinAmerica = $00000003;
15  wdNetherlands = $0000001F;
16  wdFrance = $00000021;
17  wdSpain = $00000022;
18  wdItaly = $00000027;
19  wdUK = $0000002C;
20  wdDenmark = $0000002D;
21  wdSweden = $0000002E;
22  wdNorway = $0000002F;
23  wdGermany = $00000031;
24  wdPeru = $00000033;
25  wdMexico = $00000034;
26  wdArgentina = $00000036;
27  wdBrazil = $00000037;
28  wdChile = $00000038;
29  wdVenezuela = $0000003A;
