--datdir="C:\Users*****\AppData\Local/Lnd-2" /\__ datadir?!? ___/\__ ???

'lnd --configfile=./lnd.conf' to me is a linux command.. not wind0s

If you supply --datadir as a command line parameter, you should not also have it in your config file. Try again by removing datadir=./. Also, you shouldn't use relative paths in your lnd.conf, as those will always be relative to the directory you run the lnd.exe command from. You can use ~/ as a placeholder for C:\Users\**** to shorten the paths somewhat.

Since there's already a discussion item created for this and I'm pretty sure this isn't a bug with the --datadir parameter itself, I'm closing this issue and will cross post my answer above on the discussion too.
