unable to connect using 11g rel2 client on 64 bit windows 7

[vid]

I am trying to use PL/SQL developer 8.0.4 against 11g rel2 [11.2.0.2.0] client but the pl/sql developer is not able to detect the 11g oracle home and its relative tns names. I was looking in past post and checked a few things:

I am able to connect using sqlplus.exe and oci.dll is found in by bin folder. I tried tools=> preferences=> connection => OCI library : C:\app\thotav\product\11.2.0\client_1\bin\oci.dll. It still did not work.

Following are the configurations in [oracle info]

I had a similar problem, help is only putting "C: \ app \ thotav \ product \ 11.2.0 \ client_1 \ bin" at the beginning of the PATH variable.

It was on XP, I am not sure about W7.

I hope this has helped.
