We have two thin clients with WonderWare that have a button that open an Ignition Client. This is targeting a shortcut in the C:\ to the Ignitition client. One of these works fine, but the second client gives the following error -

 ![signal-2019-07-02-143253](https://us1.discourse-cdn.com/inductiveautomation/original/2X/9/95325938e7e80e412c959b80f7867b47f85d1fb1.jpeg)

`SAXException when processing launch.xml: Premature end of file.`

We watched the Gateway logs and didn’t see anything pop up when we tried this multiple times, I assume because this error is happening prior to the gateway getting any instructions to open a client.

Any insights as to what may be causing this?

> Check for ~/.ignition/clientlauncher-data/launch.xml. I think if you delete it the launcher will create a fresh one.
