You should not hijack another thread.
Oracle 11g is not certified for Windows 8. The certified versions of Windows are listed in the Installation Guide for Windows at Oracle Database Preinstallation Requirements
And no version of Oracle is certified for any 'home' edition of any Windows version.
Other than that, I think the solution to your "same" problem is pretty well covered in this old thread. Perhaps you should open your own thread with the specifics of your own problem, which may be different. We have no way of knowing.
