I’ve recently upgrade Ignition to v8.1.3.  
After the installation, I cannot launch designer launcher.  
Found on forum

1. Reducing the “Config\Designer memory” size to 512Ko ==\> don’t change the problem.
2. The execution of the launch command located in the “designerlauncher.log” in a CMD window returns me the folllowing error:  
Exception in thread “AWT-EventQueue-0” java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0

Hmm, this seems like a bug that has something to do with the description on one of your projects. Can you open a ticket with support?
