I also experienced this error on the 4.11.0-2019-09-03 and 4.11.0-2019-09-17 slicer nightlies. Attempted the following with no avail:

- Two different Windows 10 machines (both 3rd generation Intel)
- Installing to a custom directory
- Installing to the default suggested directory
- Opening as administrator
- Opening with the ‘–disable-settings’ flag

I was however able to install and run both nightly versions without error on a Linux machine (7th gen Intel).

Edit: After reading the [post linked above](https://discourse.slicer.org/t/cant-start-slicer-on-linux-on-one-machine/8175/26), I see now it is a CPU support issue.
