Delphi 5 app cannot log in

The TOracleSession.Logon throws an exception. The Exception.Message is empty - no help there. This is an app that has been working for years! I suspect that something has changed with the Oracle installation, either a path or a DLL somewhere.

Any advice on where I can start looking would be most welcome!

TIA

Some additional info I have just learned: The owner of the box just told me that he tried to install Oracle Discoverer yesterday, but it failed. So it is quite possible that the installation changed some path or environmental or registry setting.

The empty error message is probably raised by the Oracle Client Interface. The PATH is the most likely suspect. It can also be that the Oracle Client installation is corrupt and needs to be reinstalled.
