Hi,

I have installed Oracle DB 64 bit on my Windows 7 HOme premium laptop.

I am able to connect to oracle via sql plus and sql developer

However, I am not able to connect through TOAD.

When I launch toad, its not able to find Oracle Home (Appears in RED Font)

It is not able to locate ORACLE\_HOME. When I click on ADVICE it displays the following message

## –\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

## Toad Message

1. You need an ORACLE\_HOME value in the registry under SOFTWARE\Wow6432Node\ORACLE. This value must point to the installation path of your client such as C:\Oracle\Oracle92. You may need to re-install this client.

2. No Oracle client files were found. You may need to re-install this home.

PLEASE PLEASE ADVICE

And beside using a 32 bit Oracle client be sure to take the latest 10  
(10.2.0.4.0) or 11 client. Toad is installed to a directory with (x86) in the  
name. If you use an older 10 client, Toad cannot connect to Oracle, because of  
the Oracle client.
