Can I use any folder with the datadir parameter? Specifically "c:\MULTICHAIN\node0\chains\chain0\" The reason I am asking is that when I try to run the chain with the multichaind in this case, it says "ERROR: Parameter set for blockchain chain0 is not complete."
Do I always have to use %AppData%... ?
And actually, what I want to achieve first of all is to run multiple nodes on one PS. How do I do this?
