Java is updated to last ver. Just starting the installation, it's going about 15 sec and disappears without any errors.
Here is my bug report:

An error occurred:
java.lang.ClassCastException: com.install4j.runtime.beans.actions.misc.LoadResponseFileAction incompatible with com.install4j.api.screens.Screen
