My database is Oracle 126.96.36.199 on windows 2012 64 Bit OS.
This is how I installed APEX
1. Download and unzip APEX apex_5.1.1 to apex
2. Install apex SQL>@apexins.sql APEX APEX APEX_TEMP /i/
3. Uploading images SQL>@apxidimg.sql
4. Running apex_epg_config.sql
5. And finally script apexconf.sql
I am trying to install APEX. After successful installation I am unable to load the login page http://localhost:8050/apex/ that results in error "The page can't de displayed.
Have you enabled EPG on port 8050?

Check this error with Oracle DBA or check the listener configuration.
Hope this helps!
