无法使用Delphi XE2连接到Firebird 2.5 Server

Question

I have installed the firebird 2.5 Server, created a database and want to make a connection to it with my Delphi XE2 using the Data Explorer. When I add the database details, username and password, I get the following error if I press the test connection button:

Borland.Data.TDBXError: DBX Error:  Driver could not be properly   initialized.  Client library may be missing, not installed properly, of the wrong version, or the driver may be missing from the system path.

I do not know if I need to add a .dll file to any specific folder. Please Im lost and need help.

Answer 1

You need to copy the fbclient.dll file to some folder in the PATH enviroment variable

for example In 32 bits systems copy the fbclient.dll (32 bit version) to the C:\\Windows\\System32 folder

for example In 64 bits systems copy the fbclient.dll (32 bit version) to the C:\\Windows\\SysWOW64 folder

Note : If you are using the 64 bits version of Firebird you must use the fbclient.dll file from the <Firebird install path>\\Firebird_2_5\\WOW64 folder.
