I had studio 2009 that worked on my computer. I upgraded to studio 2013, it deleted the 2009 files and now the 2013 files will not work. I have contacted support and have 3 open tickets but have not received an answer to my problem. I have windows 7 and have tried to use the studio 2013 on both office 2010 and office 2013. I have uninstalled and reinstalled several times and keep getting errors. If i try to open quizmaker or engage in the articulate tab i get the ap6mn.exe error. When I open powerpoint it tells me that for some reason it can't open articulate. Any suggestions?
