The Windows Service tries to locate the Java Virtual Machine from a non-existing directory. This happens due to the fact that the JVM is not found from the PATH - as e.g. with the installer - but from the Windows Registry or JAVA_HOME environment variable. If the JAVA_HOME environment variable points to a non-existing directory then the above error "Invalid directory name" is raised and the Windows Service will not start.

A frequent misunderstanding is to point the JAVA_HOME to the bin directory of the JVM, e.g. JAVA_HOME=C:\Program Files\Java\jre1.8.0_111\bin when in fact it should point to the installation directory of the JDK or JRE, e.g. JAVA_HOME=C:\Program Files\Java\jre1.8.0_111.
