Last year I was running Windows 7 Professional 64 bit on a desktop PC and installed and ran BlueStacks perfectly. Now the PC runs Windows 8 Enterprise 64 bit. After downloading latest BlueStacks App Player installer, whenever I am try to install, it gives me Error 25000: BlueStacks is not recognizing my graphics card and is suggesting to updating it. However, the device manager shows that all drivers are up to date. I am unable to install. Kindly suggest solutions.
