I wanted to continue working on my logisim project but now neither .exe nor .jar want to open and I even tried reinstalling Java yet I get the same "Java Virtual Machine Launcher: A Java Exception has occured." error.
Do you have any idea how to fix this problem?
I can provide extra information if needed

Please provide some more details:

  • Which exact version of Logisim-ITA are you using? If unsure, provide the download link.

  • On which operating system, in which version, and on which processor platform?

  • Which JDK version did you install? The last version of Logisim-ITA seems to have been tested with JDK 10.

Additionally, do you use any Logisim-ITA-specific circuit blocks in your design?

I am using the latest version of Logisim-ITA, that you can get on http://logisim.altervista.org/

I am having Windows 10 Version 1903 and on EM64T (if that is what is asked)

I have Version 8 Update 231

I don't think so but it fails even opening on its own without any circuit.

This Java version is definitely too old as Logisim-ITA version 2.15.0.1 was compiled against Java 10. I would suggest that you install OpenJDK 11 LTS or later, e.g., available from AdoptOpenJDK.

Downloaded the latest OpenJDK 13 from there. It's working now again.

Thank you for the quick help!
