Search Server Does not start correctly

I'm trying to do a local install on a windows machine and I'm having trouble with the search server. The appian engines all start and run correctly, and when I run search-server\bin\start.bat

I get the following:

Calling start.conf.bat
SS_JAVA_OPTS: -Xms1024m -Xmx1024m -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Duser.timezone=GMT
Appian Search Server process has been started.

however if I have a file explorer window open to the search-server\bin directory, I can see the ss.pid file be created and then immediately disappear 

the error in the search-server.log file is this:
