I just purchased PCMark 7 and ran it on my workstation.
Around what looks like the last steps in the test, a crash UI showed, titled SystemInfo.GetXml() returned null, followed by a stack trace, after clicking ignore, the app crashed.
After installing PCMark_7_v104_installer I also installed Futuremark_SystemInfo_v490_installer, so as far as I know all the apps are up to date.
The FirePro issue is with the result site, we'll get that one fixed. As for the error, I've flagged this for our programmer to take a look at.
--- Post Update ---
FirePro issue should be fixed. As for the other problem, does this also happen if you untick "scan systeminfo" in the help tab and do another run? Just trying to narrow down which component is causing it.
(such a run would then be lacking system hardware information)
