Local host problem

[JFinlayson]

I am having the problem below when trying to run GGPKG package
Local host problem.
No player detected!

Not sure how ti fix this in windows 10, something to do with settings I think.

Can you advise.

This sounds like a problem in the package.
If you change the file extension to .zip from .ggpkg, unzip it and do you see the player?
If you make an HTML5 output, does it work?
