I did, but after a while during the install, it asked me if I wanted to overwrite the files. That was the sequence that created a Mac version. When I told it no, I had the Windows version and was able to play it.
Yeah, that's what I always do, unzip to the main directory I keep such games in. I then delete the temp file once I give the game a go and see it functions properly, but with this particular demo, it asked if I wanted to overwrite the files, which was weird in its own right because I had just started having the files written. I should have known then, but I never ran into such a situation. It was like the download processed the windows portion and then overwrote it with the Mac if I gave it permission to overwrite. No worries, it downloaded fine once I did not say overwrite. I am still evaluating the demo to see if I will buy the full version.
