Problem

During a CSAT Pro installation on a Windows host, the following error may be displayed during the Neo4j database setup part of the deployment:

Following this error, the neo4j database service is not present as expected in services.msc.

Solution

This issue can occur if an incorrect Java path environmental variable is set, such as from a partial uninstallation of a standalone JDK/JRE or another application’s Java instance that has since been removed. Neo4j will attempt to use this system path over the JRE included with CSAT Pro, and consequently fail to start.

To verify that this is the case:

cd "C:\Program Files\CSAT_Pro\neo4j\bin"

C:\Program Files\CSAT_Pro\neo4j\bin>neo4j install-service
Invoke-Neo4j : Could not find java at "c:\Program Files\Java\jre1.8.0_202\bin\java.exe"

A reliable resolution option method is installing a system-wide Java 8 / 11 Runtime Environment (JRE), which will update the path to a new valid & CSAT Pro-compatible Java instance.

1	Uninstall any existing JRE/JDK on the system. Note Before carrying out this step, please verify that no other applications or services on this system are dependent on the presence of a specific Java version.
2	Download and deploy the free Eclipse Temurin Java 11 JRE using the .msi Installer: https://adoptium.net/temurin/releases/?variant=openjdk11&os=windows&arch=x64 During the installation, enable the "Add to PATH" and "Set JAVA_HOME variable" options:
3	Uninstall the first failed CSAT Pro deployment using the following steps: https://csat-pro.docs.cisecurity.org/en/stable/source/CSAT%20Pro%20Deployment/#uninstalling-cis-csat-pro Skip the removal of the neo4j service (as it will not be present), and do not delete the newly set JAVA_HOME environment variable applied by the Eclipse Temurin setup.
4	Re-run the CSAT Pro installer to begin a new deployment. The previously encountered error should now no longer occur, and the Neo4j database setup & user creation will then complete successfully.
