Installere Google som default søgemaskine

Sidder på et domaine med ca. 3500 pc'er på. Jeg ville gerne have google ind som standard søgemaskine i IE8, da vi fjerner alle toolbars inden for nær fremtid. Jeg kan dog ikke få det til at virke.
Den kører en stump kode når man manuelt installere det. Jeg har fundet nogle løsninger på nettet, men de virker bare ikke :(

Jeg har indsat disse nøgler fra forskellige løsningsforslag, men det hjalp ikke. Den ene skriver dog google.dk i feltet men søger slet ikke.
