I've used my laptop without the graphics card until now. When I tried to do the steps in the suggested thread I didn't find the Intel Graphics Card in the Device Manager so I just extracted the compressed folder and ran the setup file and everything was and still is okay. Thanks to both of you and sorry for the late answer.
