Hi Sitsofe, Yes the original FIO ver 3.12 was downloaded from bluestop. I uninstalled that version and reinstall with the link that you provided and problem resolved. Thanks for your help!

And if yes, what is the solution? Where are you grabbing the fio.exe binary from? Was it from https://bluestop.org/fio/ ? At a wild guess it could be the binary was built with instructions some of your PCs don't support due to march=native... Does the binary from https://ci.appveyor.com/project/axboe/fio/builds/20011071/job/54r8b1d6u8jpcth9/artifacts work? -- Sitsofe | http://sucs.org/~sits/
