Changing computers

I bought a new gaming computer to operate MSFS, how do I transfer MSFS from my old computer to the new gaming computer? I would not like to have to repurchase.

You dont have to repurchase. You are given “license” when you purchase the game with whichever account you purchased from, whether steam or the Microsoft Store. Transferring the game itself isnt impossible, but the last time I did it, it became bugged. My suggestion is you try to transfer the core files and then download the rest. Goodluck!
