Hello Marcel,
I would prefer the installion with wamp, the package that consists of apache, mysql and php
http://www.wampserver.com/en/download.php
to my mind the installation of conquest with mysql isnt that clear for beginners as described in the manual, so I wrote a short installation guide for absolutely noobs ( my friend in that case. ).
If you are interested, I ll can send you the file for insertion in the manual.
I am working with the wamp package cause I wrote a php prog as a webinterface for the patient administration.
