I get this error.
Is that because I'm using a 32 bit version of Windows?
I'm sorry if this is obvious but the data folder of what?
You don't need to worry anymore now, I have built an installer for 32 bit as well. You can download it in the download section (file called ReTech 1.0 (Windows 32bit)). I didn't have the installer a few days ago, so there you would have had to run the exe in the same folder as the data folder, which contains all the game data necessary to run.
