HELP Paragon Props

So I wanted to check out some of the Paragon assets but I dont have the disc space to install them. My C: which is a SSD is full. There is nothing else I can delete there. I installed the Engine in D: where there is plenty of space but it seems that it insists that some things stay in C. I also didnt see the option to choose in which drive to install the assets.
So do I have any option besides going out and buying a bigger SSD ?
