You don't need a new page.
Under Kind of Project, choose HTML. Then, upload the Windows version, choose Executable for it and pick the Windows symbol. Then, for your web version, simply choose This File Will Be Played In The Browser.
I'm not sure what I'm doing wrong.
-_- When I try to do the Window version it gets rid of the web version and says the file size it too large, but it didn't say that for the web version.
**Edit: I'm dumb. The files had the same name, so of course they would replace each other. -_- So I got that part figured out. I'm just working on the file size part lol.
**Edit again: I figured it out! And it was so easy lol. Thanks a bunch for your help!!!
