Hi Alan and thanks for your help. I checked the release notes and started again. This is my directory structure:
D:\my_app\myapp.exe D:\my_app\myapp.FDB D:\my_app\fbclient.dll D:\my_app\firebird.conf D:\my_app\firebird.msg D:\my_app\IB_SQL.exe D:\my_app\ib_util.dll D:\my_app\icudt30.dll D:\my_app\icuin30.dll D:\my_app\icuuc30.dll D:\my_app\intl\fbintl.dll D:\my_app\intl\fbintl.conf D:\my_app\udf\fbudf.dll And still both myapp.exe and IB_SQL.exe give Database unavailable message (ISC ERROR CODE:335544375 in the cae of IB_SQL.exe) :( -- Adam
