This is sounding a bit like an issue myself and some others had with an Ignition upgrade: [https://forum.inductiveautomation.com/t/8-1-35-upgrade-unable-to-extract-ignition-runtime-files-classes-jsa](https://forum.inductiveautomation.com/t/8-1-35-upgrade-unable-to-extract-ignition-runtime-files-classes-jsa) I think it started with the 8.1.33 bump of the Java Runtime to version 17. I suspect that the same issue that affected our upgrade is also affecting the clients. What I think happens is that when a client is run it fetches the resources from the gateway and extracts them - and like with the upgrade for some reason the `classes.jsa` file is immediately deleted. I've just checked and on the same server we had the upgrade issue on I can't launch the designer ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/b/abfe73b5e717e9a3a97a1cfb4d375b583500db99.png) I hadn't noticed since we run the designer on our personal computers (which connect to our server). --- _[View the full topic](https://forum.inductiveautomation.com/t/ignition-designer-launcher-error-launching-application-nosuchfileexception/89493)._
