Check out the client side network; it probably relies on something in [oracle_home]\network, whereas the V8 of the network client installs in [oracle_home]\net80.

Two possible solutions:
* copy all configuration files from the working to the   expected directory (eg from [oracle_home]\network\admin\*.ora   to [oracle_home]\net80\admin\)
* introduce an environment variable that points to the directory where your network files reside: for Win'95/98/NT this is the   registry: tns_admin, value: [oracle_home]\network\admin.

It may also be that your app relies on V2.3 network s/w; in that case, install the network interface on your client as well (will work with, and
next to V8). The more I think about it, the more I tend to try this first.
