These drivers were removed from Intel download center, but they are the only ones that will run our application correctly:
Intel 4000 (Windows Vista/7/8/8.1 64-bit)

Intel 4000 (Windows Vista/7/8/8.1 32-bit)
https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=23713"
Because of this I now have to warn my customers that Intel graphics are no longer supported. If you make the driver available again I can refer them to it.
