Hey there,
As far as I can see, all you need to do is, in edit game page:
- Empire Deluxe Linux 32/64 - change from 'Other' to 'Executable, check the 'Linux' checkbox
- Empire Deluxe OSX Universal - change from 'Other' to 'Executable, check the 'OSX' checkbox
- Empire Deluxe Win 32 - change from 'Other' to 'Executable, check the 'Windows' checkbox
- Empire Deluxe Win 64 - change from 'Other' to 'Executable, check the 'Windows' checkbox
- Delete the others (the 'Itch app' ones), they weren't needed in the first place
I think that's what the user was trying to say to you in the first place (and with much capital letters usage).
The "Other" upload type is for things that are *not* your game (and are not Soundtracks, Books, Videos, etc. - those all have their own update type).
So you really want the "Executable" type, even though you're uploading a zip - that's ok.
