I have Steam and I'd prefer to use that, but I do also have EA's Origin installed, so it's not exactly a dealbreaker. Am I correct that this is not a downloadable image of a disc, but in fact a promotion from Gamefly?
If anyone's wondering, by all means jump through the hoops if you don't mind getting Gamefly and you haven't already played Bioshock. It really it an amazing game, even if the visuals are more than a bit dated.
I downloaded their client last night and grabbed the game, then un-installed it (the client) no problem. They have my email so I will probably get spam from them but gmail is pretty good about keeping that out of my in-box once I mark it as spam.
For anybody who hasn't played Bioshock yet, I recommend it!
I had some issues getting the audio to work on Windows 7 (I have the Steam version), it was missing a driver or some other file, if I recall correctly. But once it was downloaded and installed it ran just fine.
