Captivate recordings not allowing retake in KMx

Question

Can anyone give some insight on our dillemma? We have
selected Captivate as our assessment tool inside our LMS, KMx, and
we have troubleshot and troubleshot, and cannot find why sometimes
the assessment allows us to retake and other times not. And, we
have 10,000 end users to train on up to 30 courses each. Argh.
It is a SCORM package we are publishing in KMx. We are not
doing anything different, and sometimes the test allows us to
retake; other times not.
We have one file that consistently works. We cannot figure
out what the background setting is on that that isn't on the
others.
Insight of other developers would be greatly appreciated.
Thank you!

When trying to debug LMS integration issues, you should always start your testing with very simple projects, NEVER with a complete course, and NEVER only AFTER you've built the course.  With all the added complexity that full courses may have, it becomes very difficult to track down the issue.
So the first thing to do is create a couple of test projects, to make sure that even the simplest of Captivate projects will work with your LMS.  Too much complexity clouds the issues.
First try a stripped-down bare bones Captivate project with just three or four blank slides and NO interactive objects.  You want to test the settings on a single SCORM to see whether your LMS will mark it as complete, or passed, if there are NO scored objects.  After trying various Quiz settings for both SCORM 1.2 and 2004, you should arrive at a decision as to whether you need to have at least ONE scored object in your project to get your LMS to mark it as complete or passed.  Some LMSs will mark complete if the percentage of slides viewed is greater than or equal to the required slide view percentage set in Quiz Settings.  Other LMSs will never mark your SCORM as complete unless some kind of score is sent.  Since this varies according to LMS vendor, you need to test and find out what you're up against before building your course and promising how it will work.
Your second round of tests is for SCORMs that contain assessment components of some kind.  For this test you have a similarly small and simple project with just a few slides, but this time you include one or more quiz questions.  A True/False question is all you need.  The objective is to make sure that your LMS will correctly Pass/Fail this module if the Quiz is passed or failed by the user.
After verifying the required settings for Completion or Pass, you can start looking at deeper LMS issues such as whether or not you should try to use Resume Data bookmarking.  Some LMSs support it well, others don't.  And Captivate's implementation of Resume Data can cause some bookmarking issues at times.
Finally, with regard to your Retake Quiz issue:  Captivate will only allow your users to Retake Quiz if they still have one or more attempts left on the quiz during that session, AND they have not tried to Review Quiz, or jump outside the Quiz Scope at any time.  Clicking Review Quiz or leaving the Quiz Scope will freeze your current quiz and not allow retakes.  The "inconsistency" that many users complain about is often the result of doing one of these two things.  In the case of Reviewing the Quiz, most users would know they've done that.  But many Captivate developers are unaware of the quiz scope and how it works, let alone end users that are not required to understand how Captivate works "under the hood".
Hope this helps.
