I uninstalled all EPM components, deleted the C:\Oracle\Middleware directory and re-installed.
Oracle HTTP Server install is failing. This unzip "install" directory was previously successful so I know it's not a corrupt file.
I tried installing EPM without the HTTP server, then installing the HTTP server by itself, then configuring. It did not work.
Sometimes, uninstall wont cleanup all the components.
Uninstall All Oracle Application Developer components and Oracle Common home shown in program files.
Uninstall Weblogic too.
Restart server and make sure no file are existing Oracle directory.
