We’ve gotten reports that HDXPRT 2014 no longer works on newer versions of Windows 10. We ran tests in our labs and found that to be true.
At least one user has reported that the problem may be the version of CPU-Z the benchmark uses.
We’re working to track down the problem and hope to provide a workaround in the near future and a more definitive fix (if necessary) later.
Please let us know if you’ve encountered this issue and if you’ve found any ways to work around it.
