MySQL + QT4

I have windows 7 with qt4 creator and mysql libraries inside plugins folder, qt keep saying QMYSQL not loaded, Available drivers etc..
MySQL is installed with headers and libs.
@ linux (openSUSE 11.2) i have no problem to use mysql driver and connect to mysql database.

:(

What am i doing wrong?

Thanks!

Do you have the plugin at all? Run Dependency Walker on it and see if it can find all its dependencies.
