did you check the file? Maybe it is really not there.. Does it look like this? Oh yeah, look at the Karlson_Data Or MonoBleedingEdge and search for the unity player, that's what happened to me when I tried Re:Run hehe
No none of the windows 10 version comes with a in-built archive runner i have windows 10 professional in this PC (i am not flexing but it ha a 32GB ram and the new NVDIA 3080 with an intel I9)
you moved karlson out of the karlson folder just move karlson back to the karlson folder if you want the game to be on your desktop right click it and click send to desktop
