If I want change from the 2. to the 3. side of the installations-prozess, I get following message on the side:
Error at the line 0: CREATE TABLE `#__ak_profiles` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `description` varchar(255) NOT NULL, `configuration` longtext, `filters` longtext, PRIMARY KEY (`id`) ) TYPE=My ...MySQL: MySQL query failed with error 1064 (You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TYPE=MyISAM AUTO_INCREMENT=2' at line 1). The query was:CREATE TABLE `jos_ak_profiles` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `description` varchar(255) NOT NULL, `configuration` longtext, `filters` longtext, PRIMARY KEY (`id`) ) TYPE=MyISAM AUTO_INCREMENT=2

If I upload the normal Joomla 1.5 I have no problem with the install. I make tests and delete all, take new databank, but alltime the same.

I hope you can help me

It seem your host doesn't support to run quickstart ( auto increase number problem sql ) , you can ask your host for supporting ?
