The problem is here, seems HOME is not properly evaluated... perhaps
%HOMEPATH% was escaped from evaluation.

You need to setup HOME properly, which I recommend you use SETX:

http://ss64.com/nt/setx.html

SETX HOME ^%HOMEDRIVE^%^%HOMEPATH^%

The ^ around % will delay evaluation of the variable.

For the setting changes to work, you need to open a new terminal.
