Generate a report to the PowerPoint 2016 with "Merge files", and then get an script error.
Hi,
Sorry for your troubles. I believe the output to Office (beginning with version 2016) is not functioning due to a Microsoft API change. There was an end-of-life announcement about it and the support was stopped in January 2017 (v7.7). If you have an earlier version of Office, it might work.
Regards,
Matt
