Error de registro para instalar IE7

[hechicero]

Hola a todos/as. Utilizo Windows XP y me pide actualizarlo como de costumbre y en esta ocasión, se trata del Internet Explorer 7. Me da el siguiente error y no me deja hacerlo. Imagino que tendré que tocar el registro del sistema pero prefiero que me digaís qué hacer exactamente para no liarla, por favor xD. Gracias de antemano ;)

Sí, si lo tengo solamente era por instalarlo y que el actualizador de Windows lo actualizara, por eso me gustaría solucionarlo, ¿alguien sabe?
