Thanks..the second link has nothing to do w 18.104.22.168...and in the first link, the user also does not confirm the answer to my question, which is if a SIMPLE install works on Windows 7 64 bit. There is no indication of this.
It will work fine. Just try to clean the memory once and reboot the machine. Do a complete uninstall, when I say complete uninstall, I am talking about removing some oracle files manually that are left even after the software uninstall using wizard.
