Not Spark software related, but I'd recommend Arturia team to ZIP this EXE file. Many browsers, including Chrome, are complaining that EXE files are not commonly downloaded and could be dangerous, and truth be told, downloading exe file is a security risk.
We all know Arturia files are safe and all that, but my suggestion is just to avoid possible confusion. Some people won't understand this message. Besides it's very easy to click on that Discard button (see image I attached below). Some may think "discard" this message, but it's actually discarding downloaded exe file. So, in a snap 720 Mb download goes down the drain. You end up re-downloading it. It doesn't give any instructions, but one actually have to press on that super tiny arrow to chose "KEEP". That's the only way to save downloaded exe file, otherwise it will be deleted.
Also, even though it's not always the case, ZIP or RAR compression can sometimes significantly reduce the file size. Downloading and saving on internet bandwidth is always welcome.
