Logs are created in the root folder where the exe resided.
journal_datetime.log
For example journal_20181115143405.log
They will output
15/11/2018 14:59:03: Staged bulletin MS18-10-O365-DEFERRED (guid=87efd180-d73d-4bd2-91a6-93ca8437e5a1).
You can also check the Altiris Log Viewer
- "[Install Drive]:\Program Files\Altiris\Diagnostics\LogViewer2.exe"
This will have a Module column value of the exe i.e. ZeroDayPatch-8.5.exe then then whatever it is interacting with i.e. Altiris.PathcManagementCore.dll etc.
