Captivate 5 has many bugs that have been complete showstoppers for my elearning projects. Among them, there is a problem with SCORM courses that get perpetually stuck on the gray "Loading..." screen. This is because "API.Initialize" is never called.

Thanks to the detective work of Bart Lewis, we have a partial fix.

1. Publish the Captivate file as SCORM.
2. Open the HTML wrapper file with the same name as your course.
3. Find the following line of code:

   strURLParams += (strURLParams==""?"?":"&") + "SCORM_API=" + g_zAPIVersion + "&SCORM_TYPE=" + g_intAPIType;
   

4. Change that line of code to this:

    
   strURLParams = "?SCORM_API=" + g_zAPIVersion + "&SCORM_TYPE=" + g_intAPIType;
   

5. Save the HTML file and zip up all the files.
6. Upload zip to LMS.
