I would create a setup program for my Java application. It uses a MySQL database. So the installation of my program must include the installation of MySQL server 5.5, the configuration of server and loading of my database. I use Inno Setup to do this, but I found some problems. I found this code but it is a little old.

    Parameters: "-u root -h localhost -e ""use ata; source ata.sql;"; \
    WorkingDir: {tmp}; StatusMsg: Caricamento base di dati; \
    Flags: runhidden  

When I debug, it generates an error after the first statement. Can not find the specified program in the second instruction. I tried to use mysqld instead of mysqld-nt but nothing changes.

Can someone help me?
