I would no longer use APP CENTER for anything! After updating my BIOS, it had lots of 'flaky' responses... and some of the utilities would never update or if they did, would not function correctly!
I went to the source (author) of S.I.V. and downloaded the Portable 64-bit version from there; it's working just fine!
Here's the link:
http://rh-software.com/ . I downloaded it from a few different places, and all of them were identical to the latest version 5.63 from there; I did that to be sure the file "siv_5.63.zip" was a good one, it should have checksums of:
MD-5: 2BB5EBE3A7515285BFA70FB908C96AFD
SHA-256: 46C80C742A3F3DD3FFF4647213705C3C6FE266DAFB9BEDD423F512B45E38A83C
HWiFO64 is another nice 3rd party hardware information application.
