Oracle 11gR2 install & toad on windows 7 64 bit

It's been a while since I've installed Oracle. I wanted to install 11gR2 on my windows 7 ultimate system. I tried the 32 bit, but the check failed. So installed the 64 bit server, personal.
That seemed to go ok.
I then installed the client in a client subdirectory of the oracle directory. Probably not a good move. So I thought I would uninstall, but there was no uninstall in the oracle/client directory.  So, going further down the rabbit hole I reinstalled the instant client in the default directory
Then i installed TOAD10 and it didn't find any info on oracle home. It found both clients but can't start the oci.dll in either.
I also noticed there Didn't seem to be a registry home directory for Oracle in the wow  area.
I'm obviously missing quite a bit. Can anyone guide me on what to do?

I had Oracle client 11R2 x64 and Toad 10. Toad didnt recognize client either.
I have installed Instant client 32 bit, and in environment variables I've put instant client's libraries before "normal" client's.
Then Toad recognized Oracle client.

Only drawback is that it does not display a list of availabla TNS records when making new connection, but it works when you type one in...

Hope this would help you...

So could I install the 32 bit client and leave the 64 bit?
Should I install the 32 bit in a separate folder?
What/where do I type into toad?
I'm thinking I should have installed the desktop rather then the server. Is that an issue?

Toad needs 32 bit client as far as I know, so you can do either install 32bit instant client and leave 64bit normal client, or remove all clients and install 32 bit client.
But if you have already database installed you dont need client, just put instant client 32bit and that's all...

I never used desktop version of database, I allways used server...
On my laptop win7x64 i have 64bit client, and 32bit instant client.

Always put into separate homes, only exception would be if you put client in the same home ad the database IF they are the same version and architecture.

Great - thanks.
TOAD did verify that a 32 bit client is needed.
