Good day, everyone! I would like to seek some help regarding with the recommended version of Oracle client. Currently, I have an x64 Application on Windows 7 x64 Enterprise. I would like to know if what will be the recommended oracle client for Windows 7 x64 Enterprise. I tried installing Oracle 11g and it seems that it is now compatible with the environment. Upon installing, error is showing: Oracle Database 11g is not certified on the current operating system. Thanks for the future help!
