Hi all,


I've followed the download instructions for SQL Developer v4 as per the download page (

Install instructions:




I've  installed SQL Developer requires JDK 7 (jdk-7u25-windows-x64.exe) - with no issues.

I've also downloaded and unziped to to C:\Program Files\


SQL Developer successfully starts, but when I try to connect to a data source, I get the following error:


Status : Failure -Test failed: C:\Oracle11g\product\11.2.0\client_1\BIN\ocijdbc11.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform.
