A FreeMind startup failure can in general have different causes. But one cause can be an update to Java 24 (or later); FreeMind 1.0.1 does not run with that Java version. If you use Java 17 through Java 23, you need to add switch "-Djava.security.manager=allow" to the Java invocation to make FreeMind run, e.g. in freemind.bat.

Store node scripts in their own XML element rather than in user attributes

Remove scripting from physical styles/patterns
