I installed 12C Enterprise on my laptop that has Windows 7 Home .The installation process went fine and I was able to connect to http://localhost:5500/em (even used). But, once I powered down my laptop and brought it back up the next day, I couldn't connect ('the page cannot be displayed'). So, I uninstalled oracle and then tried the process again. I could initially connect to 5500/em but after rebooting or powering down the machine, I could not find http://localhost:5500/em.
Can anyone direct me to some specific documentation with this or has anyone conclusively solved this problem to the end????? Thanks for any help.
