I have a Ignition project that suddenly starts launching multiple instances at a time. This is a single client license so if multiple instances open we get a bad session and the HMI doesn’t work. We have restarted the computer and still are having the same issue.

OS: Windows 7  
Ignition 7.2.5 (b76)

When do they start launching? After using a shortcut? After launching from the gateway page? After reboot?

I have a similar issue, but it is due to the operator launching it more than once. Is there a way to make sure only ONE instance is running at a time on a specific client machine?

No, there’s not any built-in way to do this. It’s not a bad idea though.
