I downloaded the file at 2017-12-24 11:13.05 UTC, checksum was correct.
As normal with all downloads, I ran the download past Defender and MWB, they reported no threats found, and then past Virus Total, its results were the same, viz:
On this occasion I also ran the git URL through Virus Total, as far as I could tell this was the first time VT had scanned this URL, it gave this result

I can't explain why the results are different, nor why the Last Analysis times are as they are
No problems with installing - didn't uninstall first.
