I tried the link you posted. I got the same broken web page saying "No file found". I used both Chrome and Firefox and Edge browsers (latest editions on Chrome and Firefox). I am using Windows 10 Pro Creator's version. I received the "No file found" because the web page probably recognized I was not running a Windows 8.1 on my computer.
This driver is strictly used for computers running Windows 8.1.
out of curiosity, use a windows 10 computer and see if it works. On mine, I got the No File Found when I clicked on the x64 Windows driver download link. Someone else posted a link (email from AMD Forum) , also from a Windows 7 computer and it said to work. I clicked on the link from the Email from AMD Forum and came back as some sort of JIVE error at the website. Could it be somehow related to JAVA coding?
Curious...I don't have any Win10 computers...just Win7 and Win8.1....no problem using either. I suspect a Microsoft problem. You might check and see if any reports are coming in > How to report Windows 10 bugs to Microsoft?
Used Windows Feedback App on Windows 10 and sent a problem through it. This is what I wrote when asked for more details:
http://support.amd.com/en-us/kb-articles/Pages/OpenCL2-Driver.aspx - The download link for Windows x64 goes to a web page saying NO FILE FOUND. AMD Forum Kingfisher mentioned he had no troubles downloading from the link using Windows 7 and Windows 8.1. But I am using Windows 10 Pro - Creators version and the link does not work. I used Edge, Chrome, & Firefox (All latest editions) and received the same results.
Just notice I keep spelling your name as KingFisher and not Kingfish, Will try to correct that in the future. It just so happens that a bird species is called Kingfisher which is where I keep getting your name confused with.
