I can not connect to a oracle 10g database using the 32bit version on a 64bit operating system. I have installed the software using Admin privileges and I have even attempted to run the software with Admin privileges. I have triple checked all the connection parameter details, and I get the Can't initialize OCI. Error -1 error message when I attempt to connect. When I have TNS ping via the Toad software is just states that the listener is not found.
