This one was a scary one. I upgraded to office 2014 today. Right after I did that articulate wouldn’t open. So I reverted it back to Office 2010. However, it no longer opened quizmaker within Powerpoint. The scary part was that it wouldn’t even insert a quiz which meant I couldn’t create modules with quizzes. This would’ve been a serious problem when working with clients. I spent several hours trying to troubleshoot from the links given in Articulate (clean registry, delete project.log, uninstall, etc.). I even reinstalled Office with no luck. Thankfully, it occurred to me that I could try a system restore. Thank God it worked. I did not want to wipe my computer and do an entire clean install. Whewww. Close one.
