I have been trying to figure this out for 2 weeks. I have googled it and all. I have app on the windows store. they were done in unity, sent over to vidual studio, packed into 86/64/arm packages and uploaded to the windows store. From when I understand a person needs windows 10 to use them (if not let me know). So, I was wondering if you could also upload a pre-windows 10 exe to the windows store as well. I heard you could. If so, then how?
