Morning JB, hope all is well. I may not be in the program but I sure can provide some clarity into this, as I am an IT engineer. Due to the way Steam works, basically it will only allow one install of a game on a device at a time. I suppose one way you could get round it is using a drive (or partiton on a rather big drive) with a dedicated Windows install for TSW or potentially a Virtual Machine (this would comprimise your performance though, so not recommended). There are ways to do it but it either is gonna be comprising your performance or your bank account. Hope all this makes sense.
