During the installation I recive the next message

Encountered database error attempting to load UDF library onto PostgreSQL, clean schema before running again.

Exception in thread "main" org.postgresql.util.PSQLException: ERROR: cannot use PL/Java before successfully completing its setup

Hint: Check the log for messages closely preceding this one, detailing what step of setup failed and what will be needed, probably setting one of the "pljava." configuration variables, to complete the setup. If there is not enough help in the log, try again with different settings for "log_min_messages" or "log_error_verbosity".

I check again and again the setup in the postgresql.conf and are the next.

pljava.classpath='C:\\PostgreSQL\\9.6\\lib\\pljava.jar'
pljava.vmoptions='-Xms32M -Xmx64M -XX:ParallelGCThreads=2'
work_mem=5MB
pljava.libjvm_location = 'C:\\Program Files\\Java\\jdk1.8.0_171\\jre\\bin\\server\\jvm.dll'

pljava.jar location

jvm.dll location

And all the environment variables has been defined
