Upload Exe Files

I would like to offer website visitors an application .exe download (for trial software I have built); is this possible with this plugin?

If so, I have added the extension .exe under the custom file type facility as follows:

Description: executable

File Extension: .exe

Mime Type: ?application/x-msdownload

After I click the ‘Save Changes’ button, my custom file type is not transferred to the extra file type list.

Do I need to check any of the options at the top of the list (e.g. ‘Check only file extensions…’)?to enable my custom type?

I seem to be able to upload my setup.exe file to the media list. However, after running through the upload process, it does not figure on my media file list.

Thanks in advance for any advice.
