   > Is it possible that Clouseau isn't loaded at this stage, so that the 
"ping" failed?
   
   I am not sure about that.  To me, the error message above suggests that 
`erl_call` itself cannot establish connection to the Clouseau node because it 
was not able to create the missing Erlang cookie.  For what it is worth, 
[Clouseau always uses the `HOME` environment variable to determine the location 
of the 
cookie](https://github.com/cloudant-labs/clouseau/blob/master/src/main/scala/scalang/Node.scala),
 but [`erl_call` uses the combined value of the `HOMEDRIVE` and `HOMEPATH` on 
Windows](https://github.com/erlang/otp/blob/7bbd03d2ee872c13e3cc0104b87444f3ead3607b/lib/erl_interface/src/connect/ei_connect.c#L2835-L2852).
   
   > How does Clouseau gets started? We only have `$env:CLOUSEAU_JAVA_HOME = 
"${toolsDir}\${java8Build}"` as var to point to a jdk8.
   
   I believe that should be sufficient.  This is out of my concern at the 
moment.
