Intel HD 4600 installation error

[LBish]

HI

I have currently installed Intel HD Graphics driver version 10.18.10.3345

When I try to update to latest version 15.33.18.64.3496 downloaded from here:https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3720&DwnldID=23714&ProductFamily=Graphics&ProductLine=Laptop+graphics+drivers&ProductProduct=4th+Generation+Intel%c2%ae+Core%e2%84%a2+Processors+with+Intel%c2%ae+HD+Graphics+4600&DownloadType=Drivers&lang=eng https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProdId=3720&DwnldID=23714&ProductFamily=Graphics&ProductLine=Laptop+graphics+drivers&ProductProduct=4th+Generation+Intel%c2%ae+Core%e2%84%a2+Processors+with+Intel%c2%ae+HD+Graphics+4600&DownloadType=Drivers&lang=eng, I get some vague error message saying Installed driver is not certified for this computer. Request appropriate driver from your computer manufacturer.

Forces exit. I don;t understand, download page says

This download is valid for the product(s) listed below.

Thanks kevin_intel for answer. Uninstalling existing driver actually did resolve the problem.
