I have downloaded v.1.6.1.4_00 from all four current links, #1,#2,#4 & #7. The download files from 1, 2, & 7 do not match the posted SHA256 sequence.

The downloaded file from #4 however does match the posted SHA256 sequence.

I ran all 3 of the other downloaded files through both Avast and Malwarebytes and found no problems but I thought you might want to address this issue on your end.
