Hi everyone, I have this Ignition Gateway 7.7.2 installed in my local system. This version requires to have java 8 version installed. When I tried to launch my application using ‘clientlauncher’ it didn’t showed. I suspected that this issue is somewhat related to the java version installed in my system, so when I’ve checked the Gateway Java Detection it says: Ignition was unable to automatically detect what version of the Javatm Platform is installed on your computer. Please ensure that Java 6 or Java 7 is installed… Does this mean that ‘clientlauncher’ requires java 7 or 6 installed to use it? why not using java 8 or latest version instead? This will be a problem if you have java 8 on both Server and Client system with using ‘clientlauncher’ to launch each application. Anyone can help us on this? Thanks. ---

What operating system are you using? ---

I assume you are referring to clientlauncher.exe? It definitely runs with Java 8, so that is not an issue. Also, the Gateway Java detection doesn’t always pick up the Java version on the local system, so I would ignore that. If you are using clientlauncher.exe, check /.ignition/clientlauncher-data/clientlauncher.log for any errors. ---

You are right that the clientlauncher will run but the project didn't launched at all. I'll be checking on the log if there are some errors thrown in there. Thanks for the response. ---

@mgross, sorry for the late reply. Here’s what I’ve got in the log file after I tried again to launch an application. It still not showing up.

Ok, so the issue is that the client itself is not starting. The next step is to run that Java command at the end of the log in a terminal, like so: ```auto java -classpath C:\Users\dlaki7130346\.ignition\clientlauncher-data\launchclient.jar -Djavaws.sr.gateway.addr.0=10.81.67.164:8088/main -Djavaws.sr.scope=C -Djavaws.sr.launchts=1429179433188 -Djavaws.sr.main=com.inductiveautomation.factorypmi.application.runtime.ClientLaunchHook -Xms32M -Xmx256M -XX:MaxPermSize=128m -Dsun.java2d.d3d=false -Djavaws.sr.project=ConfigEditorTest -Djavaws.sr.screen=0 com.inductiveautomation.ignition.client.launch.BootstrapSwing ``` Any exceptions that occur when starting the client will show up in the terminal. ---

Hi All, Sorry for the late response. This issue had been solved after we updated/upgraded our Ignition Gateway from 7.7.2 to 7.7.4. All applications we have are now showing when using clientlauncher.exe. Thanks for all the help.
