In the guide lines it says:

Only select platforms your project directly runs on

Do not select a platform (Windows, Linux, MacOS, Android, etc.) unless you have a program that runs directly on the respective operating system or device. 

Where do you set the platform (Windows) that the game runs on? I looked under Meta-data and there is no pull down or choice to set it. I looked under tags and there is no Windows tag.  The only choice for "Kind of Project" that is appropriate is "Downloadable".  What am I missing?

Originally when I set up the project, it was going to be only a flash program (SWF) that was run in the browser. But I ran into some issues, so I decided to make it only downloadable with:  a standalone Windows executable, a flash program (SWF)  and a Windows Flash Player.  Do I have to start over again specify the Windows Platform?

Thank you for any help you can give me with this issue.
