I've purchased and downloaded and installed all the Myst games from the Kickstarter and they all run fine but I only just noticed that Myst V End Of Ages has the Blue and Yellow Shield Icon but none of the others do. Does anyone know why this might be and how I can get rid of it?

Thank you.
I'm guessing the other ones need administrative access or don't.

Wouldn't really know or care these days, I long ago abandoned WIndows for nice pastures.
