Vamos a ver...mas que con el IsTool, lo que yo he hecho fue con el "Inno Setup Form Designer 1.1.2c", que te permite hacer formularios para incluirlos en la instalacion. Asi que lo que hice fue, crear un formulario donde preguntaba si la instalacion era local o remota. Si era local el alias lo instalaba con un path y si era remota con otro.

Asi que la respuesta se puede dividir en varias partes:

- primero como hacer para seleccionar entre local o remoto -> yo use ese programa.

- segundo como crear el alias -> se hace creando unas entradas al registro desde el inno setup.

Como no se si todo esto te aclara algo o no...te dejo aki el codigo...(un poco largo y lioso, te lo advierto!!!).

Si te aclara algo, mira concretamente las partes del registro y del codigo, pero ojo, la mayor parte del codigo de la parte codigo la genera el programa ese para crear forms.
