Hi  
I’m trying to start Servoy Smart Client with Servoy 2023.3.2 versión and I have this error

“net.sourceforge.jnlp.LaunchException: Fatal: Launch Error: Could not launch JNLP file. The application has not been initialized, for more information execute javaws/browser from the command line and send a bug report.
