**Note:** For some users with Windows Defender, there is a chance you may receive a false positive virus alert when downloading the file from your browser. The recommended workaround is to temporarily disable Windows Defender long enough to download the file then re-enable. You can then manually scan the downloaded file with Windows Defender (or other A/V program of your choice) and the file should scan successfully. We have reported this false positive to MS/Windows Defender and hope they will resolve the issue soon.
