When I download an adventure, I put it into a folder and unzip it. As usual all the contents are put there and I click on the 'game' it goes to the internet and opens up the downloads tab.
This is where my problem occurs, in the downloads tab there are 2 options, open and save but no matter which I choose it closes the downloads tab for a millisecond, and reopens it with no change.

So how do I play a downloaded adventure?

Do you have the Quest program installed?

You can only play downloaded Quest games if you have the Quest program installed on your PC.

@OurJud Where can I download this?
