So today is your lucky day. I was planning to do a captivate project soon, so I took interest in this issue. I’m using Captivate 2017 release and I was able to reproduce this problem. Looks like whatever mess of a script Adobe people are using fails to communicate with IE activeX inside HTMLEXE project.
Here’s how to solve it:
Go inside captivate installation folder and find a file named: AdobeCaptivate.ini
Then change the following value from 0 to 1:
SuppressIncompatibleBrowserMessage = 1
Let us know how it goes.
P.S. GDG Soft guys we’re still eagerly waiting for HTMLEXE 2018. Dealing with clients’ IE problems and HTML5 is really nasty. I personally beg you guys to release HTMLEXE 2018 as fast as you can. btw IE sucks, it’s not your problem.
