Finally got back to working on this...
Still new to Splunk, Python and the Symantec Cloud app, but it appeared like the Symantec instructions were written more for a Linux implementation of Splunk....
Anyway, I partially got this to work by:
(1) Upgrading to Splunk 7.03
(2) Downloading/Copying the Dateutil library into the \bin\scripts directory
(3) Changing the Path variable to the SEPConfig.Ini file in the ExportClient.py script.
OLD
r3_url = "https://usea1.r3.securitycloud.symantec.com/r3_epmp_i"
oauth_url = "/oauth2/tokens"
export_api = "/sccs/v1/events/export"
CONFIG_INI = os.path.join('/Applications/Splunk/', 'bin', 'scripts', 'SEPCloudConfig.ini')
NEW
## Full path to my Splunk installation
MySplunk_Home = 'C:\Program Files\Splunk'
r3_url = "https://usea1.r3.securitycloud.symantec.com/r3_epmp_i"
oauth_url = "/oauth2/tokens"
export_api = "/sccs/v1/events/export"
CONFIG_INI = os.path.join(MySplunk_Home, 'bin', 'scripts', 'SEPCloudConfig.ini')
(4) Changing the Scripted Input to reference the actual ExportClient.py script instead of the Wrapper.sh file provided by Symantec.
