I-Fluid has been developed 7 years ago now. We used an external middleware that doesn’t exist anymore (and we can't have access to the source code). So unfortunately it’s impossible for us to make an update for this game, even if we want to! :(
The game is working on most of the PCs, however you may have some issues running the game on recent Windows versions or recent hardware configurations. It may be an issue due to DirectX version, or PhysX driver version, or nVidia or ATI driver versions. Unfortunately we can’t fix these issues. You have to try other drivers, or you can find the free demo on different websites and try it before to be sure that I-Fluid is working on your configuration.
We apologize for these issues that we can’t handle.
