Error when trying to connect to a Oracle Database

[su11us]

I installed PL/SQL Developer 8.0.4 and now tried to connect to a remote database. When I try to login -- I get error: "Initialization error Oracle Client not properly installed OracleKey: OracleHomeDir: "
How do I fix this error. I do not have any oracle database or any other oracle software installed on my PC (Windows XP SP2).
Thanks.

You will need to install the Oracle Client software. This is a requirement for PL/SQL Developer to connect to an Oracle Server.

Hi,
I have the same problem,
I already Installed Oracle client 11g for windows 7 64bit
the client version is 11.2.0.1.0

when I run client sqlplus, it connect without errors.
and when I try to connect plsql developer an error message appears.

The Error Message is:

Initialization error.
Could not initialize
"C:\app\Oracle\product\11.2.0\client_1\bin\oci.dll"
Make sure that you have 32 bits Oracle client installed.

My questions are:
why plsql Developer ask for 32bit although it is installed on 64bit and the Oracle client is 64bit and working well???
is there another plsql developer 64bit ?
how to solve this issue?
thanks in advanced.

regards,

You will need to install a 32 Bit Oracle Client. PL/SQL Developer is a 32 Bit application, so it cannot interface with a 64 Bit Oracle Client.

The 32 Bit Oracle Client can communicate with a 64 Bit Server, even on the same machine if necessary. The 32 Bit client can coexist with a 64 Bit Oracle installation when installed in separate Oracle Home directories.
