I have installed a trial of Adobe Presenter 10 and whenever I try to "Publish", I get the error message: "Adobe Presenter has encountered an unexpected error working with this file...." I have tried all the tips I've found in this forum, including reinstalling (multiple times), made sure the "Presenter view" checkbox is not selected, fixed the COM add-in, etc. Nothing has helped. I am using Presenter 10 on a Windows 8.1 laptop using MS Office PowerPoint 2010. I would appreciate any suggestions. Thank you.
