I was not able to use this software. Installed it, then run PowerPoint (I have Office 2013), tried to activate, but whenever I clicked button “Activate”, PowerPoint froze for several minutes and then crashed. Tried three times, each time the same. Then tried to open Excel, which did not open at all – splash screen all the time, and message “Excel is waiting for external program to load OLE action”, for 5 minutes or so, and then I gave up. Uninstalled.
