Error" format: "Failed to create cookie file 'h:/.erlang.cookie': enoent"

Hi,
I am trying to install lorawan server 0.6.7 on a Window 10 PC, and I had error "format: "Failed to create cookie file 'h:/.erlang.cookie': enoent"" when ran lorawan-server.bat on command line console as an administrator. Please note that I don't have "h" drive on my PC, and I have no idea which file requires "h:/".
The Erlang/OTP version installed on my PC is version 23.0 that is used in this tutorial: https://community.st.com/t5/stm32-mcus/how-to-create-a-lorawan-server-on-local-pc-1-2/ta-p/49286
I also tried OTP 27, and had the same issue.
The output from erl command is: Eshell V11.0 (abort with ^G)
Any idea on how to fix the problem?
Thanks,
Olive
