Always feels nice to get a new version out the door. But in our haste, we didn't check the installers beforehand.
The Steam version of the installer defaults to the proper installation directory, however the non-Steam version does not. We will fix the issue in the next day or so, in the meantime I have taken down the non-Steam installer download. You can still download the Steam version, and manually change the installation directory if you are comfortable with that.
We apologize for the inconvenience.
The steam installer the config utility defaults to the wrong place too. I had to manually point it at the files it wanted before it would launch.
Yeah, it'll do that on first run. :( Not much of an easy way around it for now.
