Installing Oracle Applications R12 On Windows 7

March 15, 2013

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.

Blogs and forums I find to be much better written, and much more useful.
