When using HTTPS and manually selecting a driver, the "Display Results" button next to "Step 5:" does not function. This has been confirmed on two computers, both running Windows 7 Ultimate SP1 64-bit, on the following browsers:
Internet Explorer 11.0.9600.18230
Edge 25.10586.318.0 (Windows 10 Mobile)
The "Latest AMD Drivers and Software" links can be used as one workaround but I still wanted to report the issue.
