Window 10 edge - links for msi download save as man extension

I've a web site with a download http link to a .msi file but then it shows up as .man file in window 10 edge. I know you can just save it as different filename/extension but not all users will know it should be msi extension so once they download it won't work.

Anyone got this issue and know what's the fix on the website so it can shows up properly in window 10 edge? Thanks.
