I had buy the Genuine version of the Street Fighter IV. I can also make some system upgradation to accommodate the game on my computer. I can modified my computer configuration as processor to AMD Phenom II X2 3.1 GHz, Gigabyte motherboard that can have on board graphics of 512 MB and also can have the slot to add an external video card of Nvidia GeForce 9500 GT which can be of 1 GB. I am now using 2 RAM sticks of 2 gigs each. But when I try to run the Street Fighter IV, it can shows the Street Fighter IV Launcher has stopped working error.
