Using embedded, you will need to restart your application for
Firebird.conf changes to take effect. Using a full server, the service
needs to be restarted for changes to take effect.

Your error message indicates to me that your file system permissions
are not set properly. You did not indicate whether you checked this.

Does your app work when logged in as Administrator? Remember that
embedded works within the security bounds of whatever user your
application is launched as. If you are using a full server, then it
gets installed under LOCALSYSTEM which can pretty much do anything,
but if your user is a plain user, then they may not have permissions.
