Oracle Applications R12 is not certified for installation on Windows 7. The reason seems to be that Apps wants to be on a server that can do lots with domains. This is problematic or not possible with Windows 7, but easily accomplished with Windows Server 2003 or 2008.
But a few years ago, I managed to install Apps on Windows XP, even though XP is not certified either. So, why not Windows 7?
