Error during the instalation

I’m trying to install Visual Paradigm 15.0 and after the install4j Wizzard is prepared, an error occurs:

java.lang.ClassCastException; com.install4j.runtime.beans.action.misc.LoadResponseFileAction cannot cst to com.install4j.api.screens.Screen

On which platform are you trying to install VP (Windows, MacOS, Linux, etc.)? Also: when exactly does this error occur? Right after you started the installer or maybe somewhat later?

I’m trying to install VP on Windows 7 and the error occurs right after install4j is prepared, it takes about 30 seconds before i get this error.

I’m facing the same problem, is there any solution? thx
