Downloading CIS installer - two different images??

I’ve tried to download CIS Premium installer. When I clicked on icon “Free Download” at here, I got an image, named cispremium_installer_6100_08.exe. I cancelled this download, but… I got a message: “If your download did not start automatically, please click here.”. Clicking on that link is starting to download an other image, named cispremium_installer.exe
Why is this difference?

Probably just for redundancy, if one doesn’t work then the other might? The files are the same, same hash but different names.

I’ve checked the MD5 sum of them. They appear identical. :slight_smile:
(I have an older version of these files, but the older ones were different)
