Cant seem to upload an .exe file

Hey all,

I am trying to upload an .exe to grav so people can download it. I have set nginx and php to allow the correct upload size. When I try to upload I get an error that says “Unsupported file type: exe”

In the configuration under Security i have removed .exe has a dangerous file extension. I have also added .exe to the media section. Settings are attached below

Any help/tips with this would be awesome, thanks!
