error installing Perseus 1.9.1 demo

italian version downloadable from:
http://www.perseus.it/it/demo.php
english version downloadable from:
http://www.perseus.it/en/demo.php

double click on installer setup, while installing I always got this error:

---
Unable to execute file:
command.com

CreateProcess failed; code 2.
File non trovato                          [TN: File not found]

this error doesn't happen on Windows, seems related to Wine.
I attach a shot of the error.
