Can't import PowerPoint slides into Storyline 360.

I'm using the trial version of articulate 360 and have faced the same issue. I've read many threads of discussions about this issue here. And I solved it today!

First, the staff wanted to make sure if I had PowerPoint installed in my computer. I've just bought a new laptop with Windows 10 and assumed that I had it. I clicked "Start" and could see all apps including PowerPoint. So I thought I had it and I've tried all of the troubleshooting but didn't work at all.

Next, I found out that I didn't have anything about Microsoft Office in "Programs (<- Control Panel <-Windows System)". 

So, I logged in Microsoft Office 365 and downloaded all Office 365 apps. Tada!! MS Office was installed in "Programs" and successfully imported ppt files to storyline 360!

I don't know the difference between the built-in office apps (maybe it can be click to run?) and the installed apps I downloaded (is it called MSI?). Anyway you must check if you have it in "Programs". 

Hope this posting would help anyone!
