Also, it is not a best practice to have "localhost" in your listener.ora and tnsnames.ora files. It should be the actual host name, preferably the fully qualified name, as in myhost.mycompany.com.
Service "orcl" has 1 instance(s). Instance "orcl", status READY, has 1 handler(s) for this service... Handler(s): "DEDICATED" established:4830 refused:0 state:ready LOCAL SERVER
Another thing you might consider is whether the prior failed installed did not get cleaned up properly. Maybe it is interfering with the operation of you current installation. Also, try checking for errors in E:\app\PaulK\diag\tnslsnr\PaulK-PC\listener\alert\log*.xml.
