I have a school project due ASAP and I can't figure out how to make the Adobe Captivate to become a live web site to send to my teacher.
You need to upload it to a webserver or a LMS. It is has Reporting turned on, you can use SCORM Cloud, allows you to upload a limited number of files for free.
Alternative: go to the eLearning porttal, create a sample project using the button 'Post here' and include your published project (zipped by Captivate on publishing). Then send the URL to your teacher.
