Packaging for Windows and uploading to itch.io

Hi,

I have recently made a game in UE4 and I wanted to put it on itch.io, so then I packaged it for Windows. But when I uploaded my .exe file to itch.io and tested it, I was not able to run it. How do I make my game playable on .exe?

Please help, I have researched on both YouTube, Stackoverflow, and this forum but I have found no solutions.

Thanks,
