I am trying to install Oracle Express 11g, after I download the zip file OracleXE112_Win64 - I unzip it, and open Disk 1 then setup. I go through the entire install
OracleXE112_Win64
Open your browser and type instead of "http:/.127.0.0.1:%HTTPPORT%/apex/f?p=4950"
type "http:/.127.0.0.1:8080/apex/f?p=4950" you can reach home page.
you can set the HTTPPORT as 8080 in environment variables, the problem will be solved.
