i know this was posted 5 years ago, but basically what I found out is that you need to have the JAVA edition of minecraft. if you bought your minecraft off the window's 10 store, or more recently, redeemed it for free, it's the BEDROCK edition, and still doesn't support mods. I assume when you open the game, there's no launcher page and there's no text under "Minecraft" when the title screen is on, this tells you it's bedrock version, which is newer but.... no mods, no forge, etc.
