Answer these first.

Are you hosting on a WINDOWS server, as this thread's location suggests?

Have you followed the DOCUMENTED INSTALLATION INSTRUCTIONS in the docs folder of the Zencart software?

Have you created a database (and applied a username. password and full dbase privileges to it), on the server?

erm... i am sorry. i no very understand what u mean can u explan clearly ??

the setup is asking me to get a database for mysql

READ the instructions in the docs folder of the zencart software.
