Hi, well, i don't know, what happens with your installer...
But: If you want to re-activate the install wizard, look for your site.ini.append file(s). Toggle the "CheckValidity" (or something similar with "Validity"). When this is "enabled", the wizard starts, when you access your index.php . (Or delete the folders settings/override and settings/siteaccess recursivly to remove all custom settings and sart over with the wizard, too)
