Storyline 3 stuck - says "Initializing commands..." - all after the Windows 10 "upgrade

Hi, Liesbeth. Let's see if we can make this easier for you.

It sounds like your normal "user profile" on that machine doesn't have administrator permissions. In this case, make sure that Storyline 3 is installed as administrator (right-clicking the storyline-3.exe file and choosing Run as administrator), and then launch Storyline 3 normally. You can uncheck "Run this program as administrator" from the Compatibility tab so it doesn't require you to login with those credentials every time.

Let me know how that works for you!
