Sysmon Event Parsing

[suspicious_link]

I'm having trouble getting all the fields from sysmon automatically parse with the microsoft sysmon add in could someone tell me what i might be missing?

The events are coming into my home splunk instance (8.2.2) but not being fully parsed correctly, I'm pretty sure i need to use a transform, but the one I've tried isn't working (I'm pretty sure i did it wrong but *shrug* no idea if i did or not)

I've installed sysmon on my home computer and have the universal forwarder pointed to my home splunk instance.

I followed the guide i found here: https://hurricanelabs.com/splunk-tutorials/splunking-with-sysmon-series-part-1-the-setup/

As you can see in the screenshot it only extracted some of the fields and the IMPHASH value carried over into some other data.

inputs.conf for sysmon

[WinEventLog://Microsoft-Windows-Sysmon/Operational]
disabled = false
renderXml = true
source = XMLWinEventLog:Microsoft-Windows-Sysmon/Operational

output of my transform with the path:

cat /opt/splunk/etc/apps/search/default/transforms.conf

[geo_us_states]
external_type = geo
filename = geo_us_states.kmz

[geo_countries]
external_type = geo
filename = geo_countries.kmz

[geo_attr_us_states]
filename = geo_attr_us_states.csv

[geo_attr_countries]
filename = geo_attr_countries.csv

[geo_hex]
external_type=geo_hex

[xmlwineventlog]
REGEX = "Data Name\=\'(?<_KEY_1>[A-Za-z]+)\'>(?<_VAL_1>[^<]+)<\/Data>"
DELIMS = "'>"

Here's a sample event straight from _raw (looked this event over nothing seemed overly sensitive)

i think i fixed it on my own, i had some other sysmon apps installed and disabled all but Splunk_TA_microsoft_sysmon 

AND installed

Splunk Add-on for Microsoft Windows (pretty sure this is what did it)
