Enigma: Rising Tide question and SH5 Question

Hi everybody, Id like to start off by saying Im new here and have been really interested in SH5 lately. Even with what seems to be tons of bugs the mods seem to help work out kinks. Second, I didnt really know where to put this post so please dont flame if i put it in the wrong area thanks

But first question is about Enigma Rising Tide, I had it on my older computer and it worked fine, then we got a new one with windows 7. I installed it and every time I try to run the game, it always comes up with a screen saying I need to reboot for the install drivers to set in or whatever, my question is does it not work on windows 7? Id really like a sub game to play since its the only one I have.

And Secondly, to run SH5 smoothly, Im guessing you need one beast of a computer, because the graphics I have seen look extremely impressive, what would be minimum requirements for a smoothly run game? I can post up the computer specs im running on right now if need be.

Thank you all for any help
