From the documentation, it says the following

Then rename fbembed.dll to either fbclient.dll or
gds32.dll depending on your database connectivity software.

However when I rename fbembed to either of them, the program does not work.

from my log file, I receive the following

ib_util init failed, UDFs can't be used - looks like firebird misconfigured

and

bin\Debug\bin/ib_util.dll library has not been found

I am using devexpress xpo

any suggestion
