Hi Rafael!

I ran into the same problem. The trick was that the exe installer
haven't written over the gds32.dll located in the system dir, I had to
manually overwrite it. Because of gds32.dll is present for backward
compatibility and contains references to the fbclient.dll, You need the
appropriate version in your system dir. Try use the zipped package and
then manually copy the gds32.dll and fbclient.dll from the Fb \bin
directory.
