Oracle Express 11g No message file for product=NETWORK

I have installed Oracle Express 11g on my windows 8 desktop. Prior to installing I checked ORACLE_HOME was not set. After installing it still wasn't. So I created it:

ORACLE_HOME=E:\DATA\Dev\Oracle11gXE\app\oracle\product\11.2.0\server

I have not touched any other file.

When I check the services OracleServiceXE is running but OracleXETNSListener refuses to start. I need it for sql developer, etc.

Don't know if it's related but when I try and open 'get started' icon which goes to: http://127.0.0.1:8080/apex/f?p=4950 I just get a page not found and port 8080 is fine to open (as I run tomcat) despite tomcat, etc not running.

When I check the log.xml all I see is about 10 repeating items like this:

<msg time='2015-07-07T18:52:01.076+01:00' org_id='oracle' comp_id='tnslsnr'
 type='UNKNOWN' level='16' host_id='NCOMPUTER'
     host_addr='fe80::10e2:c588:6413:cf%3' version='1'>
 <txt>Message 279 not found; No message file for product=NETWORK, facility=NL
 </txt>
</msg>

I tried changing the listener file to use localhost but get the same error, as do with tnsnames.ora:
