Oracle Database Discussions

Hello all

I installed an oracle database 10G and an oracle client 10g on my demo server.
Also did I install TOAD 8.0 but when I load it and I want to connect to my database it gives following error:

Cannot load OCI DLL: C:\oracle\product\10.2.0\client_1\bin\oci.dll

These are the messages that are giving in the connect using options screen:

It says that the Home is not valid although it is correctly defined.

Can anyone help me with this problem?

thanks!
