Thanks, Mark! It worked!

I also notice something very interesting during my tests:

1. No matter if you use Firebird if a Service or Application, even without installing the guardian:

Stop the Service or do Shutdown of the Application on tray icon has zero effect!

It stays working normally on Delphi, IB-Expert and in your Applications.

You really need to completely uninstall Firebird on Windows Settings.

This is quite interesting, if the service is stopped and no Firebird server running, then how can you access the database, it might be that you already correctly setup the embedded server and the application load the embedded server

 

2. Delphi (Firedac at least) in Design Time uses BY DEFAULT Firebird installed on your machine, whatever if it is stoped or running (explained above).

On Runtime it will use the settings that you have, to use Embedded. So, stay alert: You can't use Embedded in Design Time if you have Firebird installed on or machine. You need a complete uninstall to do it.

Anyway, it works!
Thanks again.

Why is there "no need"? If you want to solve your problem, it is good to
know which libraries get loaded by your application.

I have only ever seen this error when plugins\engine12.dll is either not
present in the folder with fbclient.dll, or with different bitness
between application and client, or client and engine12.dll.

When it is prefixed with a # it is a comment, if you want to try with
Providers = Engine12, then you need to remove the #.
