Publishing Issues from Webserver

Just so that we understand each other, this is NOT Adobe support.  It's just a user forum made up of people that all use Captivate professionally and help each other out when able.

The last couple of updates to Captivate 9 introduced a big change in the way PNG and GIF images were rendered in HTML5 output.  Previously the images were just images, but in the later updates the PNG images in particular were generated from JSON files, hence the need to enable JSON on servers for HTML5 content published after that update.

I'm not aware of any major changes to the way that PowerPoint content in Captivate was rendered in output between Captivate 9 and 10.  But it is important to note that if your PPT slides included custom animation effects, then those effects were not likely to work as expected once the slides were pulled into Captivate.  In older SWF output the PPT animations were converted to animated SWFs.  But in HTML5 output the animations were likely to just end up as static PNG images (in my experience). 

Due to these issues you won't find too many experienced users here that prefer to use PPT import.  In fact we generally discourage new Captivate users from using PowerPoint as a starting point for elearning projects as there are just too many things that can go wrong and your options are limited (especially around animation).  The better way to develop elearning is just to use Captivate's default slides and objects from the ground up.

My gut feeling with your current project issue is that there is either corruption in the project or else we haven't been told everything there is to know about what the original PPT deck contains.  That might explain why this weird scaling issue is occurring.  I've never seen that before as far as I can recall.

Eric is correct. My bad.  There is no SCORM imsmanifest.xml file involved in this particular case.  However, what I said above about the multiscreen.html file probably redirecting to the wrong output is still likely, unless you are launching the output directly from the index.html file, which then does launch the HTML5 output, not SWF.

All Captivate versions since late Cp 9 now use JSON files in the HTML5 output to deliver PNG or GIF images.  So if your web server is not set up to allow JSON files, that can prevent the output from playing and cause the endless loading issue.  (The loading GIF itself is not delivered by JSON.)

Your setup is somewhat unusual, involving multiple systems.  So, to first work out whether or not the root cause of this issue is external to the course module, I would suggest you find another web server where you can upload your content and test from there to see if it still misbehaves the same way (with enlarged PPT images etc).  That web server would also need to have JSON files enabled.
