If you have Java installed on your home computer you can go to your control panel and then down to the "security" section and then the SSH/Shell Access. Then change directory into the framework file which would be something like cd /home/(account name)/public_html/yii_directory/framework and it should be familiar to you then with php commands using "php" rather than "php.exe".
