Windows 11 and Storyline 3

As I posted above, I ran into a problem launching AS3 on a brand new laptop which came with Windows 11 pre-installed .... and which is now solved.

I received very prompt and excellent help from Articulate Support. In particular Ian Saavedra spent a patient 90 minutes working remotely through a whole series of possible causes and solutions without success. He escalated the case to a colleague (Clara) who immediately got in touch with the offer of an online meeting to continue to seek a solution.

in the meantime, as we had exhausted all the troubleshooting options we could think of, I did a complete reset on the laptop and reinstalled Windows 11 (which, as I mentioned, came pre-installed from the store) ... and AS3 launched perfectly.

I am really grateful for all the help from the Articulate team and other insights from fellow designers on this forum
