Vision Client Launcher Install, Ignition 8.1.10


Recently, I tried to setup Vision Client Launcher on a windows 10 PC. I have installed Vision Client Lauchner on numerous computers without trouble. Unfortunately, I have hit my first problem which I will try to describe below.

I navigated to the gateway and downloaded the Vision Client exe. The install seemed to go well until I tried to launch a project I get an error message “(see path below) jvm.cfg” is missing. I tried to remove and reinstall vision, but there must be some data still on the PC. When I uninstall and reinstall, the projects are still there.


Seems this is the folder which is missing the files. Does anyone know how I can 100% remove everything ignition vision client launcher install has placed so I can try again? Or is there another solution like copying the folder from a working machine to the not working one? I would love to understand where I went wrong.

Usually, deleting the C:\Users\YOURUSER\.ignition\cache\ folder should do it. Deleting the .ignition folder is a bit more of a nuclear option.

The project info is stored in a json file, But I don’t quite remember where since I’m not in front of a Windows machine :wink: . I kinda doubt that that is where your issue is.

Thank you, I will give your suggestion a try. I’m not afraid of going nuclear if deleting the cache folder does not work.

You can start with more surgical. If the error is saying something about a jvm config file and highlighting a particular runtime directory, you can just delete that one runtime. The next client or designer you launch that requires that version will automatically download it from the gateway.

Deleting the folder fixed this issue for me. Thanks Paul!
