<br>
it seems that HOMEPATH environmental variable is not defined for your account.<br>
<br>
> I'm using Windows 10.<br>
<br>
Based on [1] HOMEPATH should be defined on Windows 10 too.<br>
<br>
Haven't you unset HOMEPATH for your account by chance? Try to set<br>
HOMEPATH pointing to your home directory.<br>
