Hi Taazz and Laguna!
Thanks for replying.
Maybe its for the security as you comment. I was working with the Database in Windows XP 32b without problems. But the hard disk of that machine goes down and my client buy a new computer with Windows 7 64b installed on it. I Try to open the Database with Version 3.0.2 of Firebird but this problem emerges.
I search in the Internet and found this page:
http://tracker.firebirdsql.org/browse/CORE-4899 that contain a batch file that you can run to solve this. But I try with no positive results.
What I finally did was desinstall Version 3.0.2 and install Version 2.5.3 of Firebird and the Database opens without problem.
Well, as long as I work with my Database. I decided to use Firebird Version 2.5.3 despite of being an older Version.
Now, I have the problem that my ODBC 32 driver doesn't work with this version.
I have to search for a 64 version instead.
Hope that this will help you too Laguna.
