This can be handled by adding an exception to Java security settings to allow execution from that URL. - Also, it would have to be done on every machine. - Also-also, you might have to do it again if Java gets upgraded. The correct answer is don't use Java Webstart. Webstart is dead. Use a client launcher with java built-in. What version is this? ---

What version of Ignition? If it's a 7.9 installation, you can go to the latest 7.9 version and have the built-in Java. ---

Yes, it´s a 7.9 from 2019, how can I switch to the built-in Java? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/b/4b722c18008a999ba0927c0ada515a4d2cb39200.png) ---

I install this version on my computer and should work fine? ---

I've not had an issue within the same major revision. You will still need to go to each client and install the launcher. ---

It's probably still worth upgrading to 7.9.21, but the Native Client Launcher started embedding Java with 7.9.10. > **[Native Client Launchers | Ignition User Manual](https://docs.inductiveautomation.com/docs/7.9/clients/native-client-launchers)** > > The Ignition Gateway contains downloadable native executables that can launch Clients directly without invoking Java Web Start.

Ok, thans @JordanCClark and @avaughn Will check it out if I still have problems after add an exception to Java security settings. This upgrade Ignition solution seem more trouble as I would need to check clients afterwards. Cheers! ---

There's also this KBA that goes over the available options and provides the information you would need to set in the Java Security Settings if you decide not to use the NCL.
