I just went with the default install location. I deleted the folder and reinstalled quite a few times but I always got the same error. I redownloaded the file too to see if that did anything but it was the same. I could try installing to another location to see if that makes a difference.
I don't know if I'm doing something wrong but after installing the game and trying to run it, I get a loading error. It fails to load IconSet.png and I think Balloon.png once.
