It’s so nice to hear from you again. Let’s get back to the problem where you’ve been stuck.
Please unzip the Articulate Presenter SCORM package, copy and paste the "imsmanifest.xml" file in the unzipped folder and then again zip the folder using any file compressor software such as winzip, winrar, etc.
If you don't have the imsmanifest.xml, then you need to re-publish SCORM packages with SCORM authoring tool Articulate Presenter where the imsmanifest.xml file is in the correct place.
The link we’ve provided you have the detailed description of how to create the SCORM package. Please have a look at this:
I hope this’ll be of your help. Looking forward to hearing from you. Keep on Moodling!
