Oracle issue - 64-bit and 32-bit -IMP - PLZZZ HELP

Question

Dear all,

My machine is 64-bit Windows 7 with 8GB RAM.

I have installed Oracle 11g Client - both 32-bit and 64-bit.

I am using SQLDeveloper to connect to the client.

Toad is not working - Error - "Cannot load oci.dll file" - I checked in BIN Folder - FIle is there.

My Queries are -

1. My portal has backend as Oracle. WHen I run it on my machine to debug, it gives error -

BadImageFormatException. This will occur when running in 64 bit mode with the 32 bit Oracle client components installed

 

Exact Error Message - Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.

 

How to solve this ?

2.In SQLDeveloper - How to find which client the SQLDEveloper has connected to.

3. TOAD - From where to download TOAD That is compatible with Oracle 11g client.
