hello 
, i post my solution to create the application via yiic on Server2go (Apache, mysql, sqllite, php) on Win Xp.
I'd problem with the library php_pdo_pgsql.dll on the php.exe, so i changed the php.ini on the folder Server2go/server/Apache that is the setup-file of the All_in_one-application, but not work.
So I changed the value of path of the php.exe in the yiic.bat file, and I delete the library pdo_pgsql from the code of the php.ini inside Server2go/server/php.
now it's working.
bye
but I don't understand why it not working this library.
