Cannot generate results
I get this error message. How long are you suppose to run the demo for? I usually run it for 5 mins before hitting esc. I have an AMD 7850 card on Win 8.1

Unexpected error

This error is something I have not seen before. Could you describe your system configuration?

Free version has three tests - Ice Storm, Cloud Gate and Fire Strike, each of which have several graphics tests. At the end the scores are shown in a browser.

In Advanced Edition you can choose which tests to run, depending on your hardware.


Edit: If this happens when you exit, that would suggest that your system does not have proper browser set as default and 3DMark is trying to open a browser window. Most commonly we've seen this with Windows 8 and Google Chrome which, for whateve reason, doesn't set itself properly for other applications to start (hence the "class not registered" error)

Hi Jarnis, i'm using free version of 3dmark and i have similar problem as described here, full error message is:
"Online validation failed
System.ComponentModel.Win32Exception (0x80004005): Class not registered
at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start(ProcessStartInfo startInfo)

at Futuremark.DMark.UiCore.Code.ResultManager.Post(OnlineInstructions onlineInstructions)
at Futuremark.DMark.Gui.MainWindow.PostResultWorkerEntryPoint(Object param)"

According to your words it seems like default browser can be a problem. I'm using windows 8.1 enterprise x64 and my default web browser is vivaldi x64. It is fairly new web browser based on blink engine and it hasn't reached final version yet but to me it is fully usable as every-day-use browser. Could you please add to 3dmark support for vivaldi being default web browser?
