Ensure you have JRE or JDK installed and the JAVA_HOME environment variable is pointing to the Java installation directory. Oracle Java 1. 8 JDK is required.



The TeamCity server requires JRE 1. 8 to operate (download page), the agent can run with Java 1. 6-1.810, but Java 1. 8 is recommended. Recommended The recommended Oracle download is Java SE JDK.
It is recommended to use the 32-bit installation unless you need to dedicate more memory to TeamCity server. Please check the 64-bit Java notes before upgrade.
If you configured any native libraries for use with TeamCity (like a .dll for using Microsoft SQL database Integrated Security option), you need to update the libraries to match the JVM x86/x64 platform.
