We have checked permissions and that doesn’t appear to be an issue. Sugar is running via IIS on Windows Server 2016, and IUSR has full permissions. Sugar/SugarChimp is working in this environment currently, we are simply trying to upgrade SugarChimp as this is a prerequisite to updating our SugarCRM instance.
I have emailed the log files to email@example.com as advised on 12/17/2018, and again on 1/4/2019 but have yet to get any response. If you can find my emails with the logs, within the logs I attempted to install SugarChimp again on 12/17/2018 at 15:54PM and left it until 16:05PM which is when I attached the logs to the email.
