Articulate 360 will not load

Hello.

I am in dire need of help.  When I am trying to open the A360 desktop app to install the software, it crashes.  I look at the information in the file it wants to send to Articulate and this is what it says.

<?xml version="1.0" encoding="utf-16"?>

<ErrorReport xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</ErrorReport>

Can anyone help me to understand what is going on?

Thank you.
