Today I install application and copy "dbexpoda40.dll" and "dbxadapter300.dll", but when start application i receive the message "the not load dbexpora.dll (126). It may be missing from the system path".

My Delphi 2007.

In the Client computer with delphi installed is OK running.

In the Client computer with mysql "dbexpmda40.dll", is OK.

So with "dbexpoda40.dll" not running.

What to do?

Check LibraryName property of TSQLConnection component. There should be 'dbexpoda40.dll' (not 'dbexpora.dll'). To set correct properties, you can double click TSQLConnection component and select 'Oracle by Core Lab' driver in the dialog box.
