My oracle.dataaccess.dll is not supported on x64 machines. I searched everywhere - but all I could find was the x86 version.
Does anyone know where I can get it?
You can download "11107_w2k8_x64_production_client" from oracle, and after installation you will find the file in the installation directory.
