Because it either copies dlls to the system (syswow64) directory which
is in your path or changes your path and adds the location of the dlls
(c:\program files\firebird...whatever\).

I'm describing a method that does not mess with a user's path but
contains the dlls in the application directory. I think this is much
safer than fiddling with a users's environment, because it can break
other applications and it is not as robust (imagine an interbase
gds32.dll in an earlier path of the path overriding the fbclient.dll you
just added to the path).

Not a problem on your own dev machine but problematic when messing with
end users PCs that get your application.

I used this.
