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 #.
