Hi, we’re trying to install a client on a mac pc but we are running into this issue. Do we need an older version of java to install it? The ignition client we’re trying to install is using a 7.8 version ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/a/aae89249510fb9d9d468d18d06360da97d92ed9d.png) We’re trying to install it on a macOS Catalina, and the java version we have installed is Java 8 Update 271. ---

Are you sure Java 8 is installed and that’s the version of Java on the PATH and being used to launch? If you open a terminal and run `java -version` what do you get? ---

This is what we got from the client ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/e/2e7b14b4e7d833be4d015a6aa4e1962287fdb8bc.png) Checking now what we see on java -version ---

So that’s going to be the issue then - they are launching with Java 15 instead. I’m not sure how to set the Java version on the path system-wide… Are they launching via JNLP or Client Launchers? I think the launchers allow you to specify a path to the Java version to launch with… ---

They’re trying to lauch with client launchers, would launching via jnlp be easier? So we just need to set the path for java? ---

Launching with the JNLP will probably fail as well without the correct version of Java being on the path. ---

I thought I would see atleast 2 versions of java but i’m only seeing one here. So I’m guessing java 8 version did not get installed? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/e/2ec89a7d62fb07948bb96f88987c2c437fa707b4.png) ---

It looks like their latest version of java is 15.0.1 so we just set JAVA\_HOME to that version. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/0/b028765a947c2815547162c3fec769224e020260.png) Does the older version of ignition does not work on that? Or is this still a java issue? ---

The older version of Ignition will not work on any version newer than 8. ---

I see so we need to downgrade. Let me try that ---

Do they need to install the jdk or jre version? Cause it looks like its looking for jdk ---

Either should work but it’s usually easier to find a JDK to install. ---

I’ll mark this post as solved. What we did was we downgraded to Java 8, completely uninstalled java, installed java 8, then to make sure, we set the java\_home path to point to java 8. ---

Thanks for coming back to update. If you ever get a chance to upgrade to newer versions of Ignition this whole Java version thing is solved - we include the necessary Java runtime in both the gateway and all the launchers, and the end user can have any version or no version of Java installed, it doesn’t matter.
