No ZIP File when publishing Scorm 1.2 in New Captivate?

I’ve gone through the preferences menu, enabled reporting, configured the settings for scorm 1.2 as desired, but when I then go to publish, I’m not getting the zip file to upload to the LMS- just the preview file. I’ve done this process successfully with other projects, but this one doesn’t seem to want to work properly. Any ideas what I’m doing wrong here?
