Afterglow not working on Splunk 7.1.1 (Windows)

[ng87]

Hi all
I'm having issues getting Afterglow to work on our dev Splunk instance. Currently running latest version of Splunk ( 7.1.1) on Windows and whatever version of Afterglow you download off the official website. I have installed ActivePerl and Graphviz and even added them to Windows PATH.
Here is where the software is installed :

Perl Location : C:\Perl64\
GraphViz Location :C:\Graphviz2.38\

Path entered into Afteglow Config ( App settings in Splunk)
Perl : C:\Perl64\bin
Graphviz : C:\Graphviz2.38\bin\

When performing a generic search on firewall logs its returning thousands of events however there is an error message that reads:
AfterGlow was not able to generate a graph. Please check the neato directory in the AfterGlow Setup.

Anyone have any idea how to fix this issue ?

The "Troubleshooting" section of the AfterGlow app page (https://splunkbase.splunk.com/app/277/#/details) give some steps to try. There's also contact information if you need help from them.
