Using Zookeeper 3.5.6-bin, on Win10, java8
PATH= ;%ZOOKEEPER_HOME%\bin;
ZOOKEEPER_HOME=C:\apps\Apache\apache-zookeeper-3.5.6-bin
dataDir=C:\appas\apache\apache-zookeeper-3.5.6-bin\data
I am starting with zkServer start
ERROR:

ZOOKEEPER_HOME etc seem correct?
Update/Resolution
zkServer [start] - is a documented legit way to start - but this gives errors - cant figure that out why. So just zkServer to start.
Port 8080 conflict for admin server: You can kill the existing process on this port (requires a bit of doing). Or you can start admin on different port (or even disable admin server completely). This is not clearly documented in the Docs - but check here
In a joint effort the solution is to run it without start, just
> zkServer
..and to ensure nothing else is running on port 8080 for the AdminServer to be able to start, avoiding this:
Unable to start AdminServer, exiting abnormally
org.apache.zookeeper.server.admin.AdminServer$AdminServerException:
