Powerful software for more experienced elearning developers

I use Adobe Captivate to develop interactive courseware for courses that assist Airmen in getting qualified in their respective career fields for the Air Force. The software has proven to not be very intuitive and requires a large amount of programming capabilities in order to get it to function. We have found that the responsive aspect actually makes development more difficult, especially when utilizing the fluid boxes. It can also be rather glitchy when uploading in SCORM files. Due to security requirements we cannot use the associated assets due access issues.
