JES no longer launches

[JoshS-dev]

I have been using this version of JES for a bit now, and only just now, the splash screen pops up but the program does not open truly. The last time I used it was the beginning of last month, no updates to JES since, and uninstalling and reinstalling did not help.

What operating system are you using, and which version of JES? I most often see that kind of behavior (splash screen comes up and then JES crashes) when there's a disconnect with Java. Did you install a Java update during that time? - Mark ------ Mark Guzdial, mjguz@umich.edu - Professor of Electrical Engineering and Computer Science, and Engineering Education Research, College of Engineering and Professor of Information, School of Information (courtesy) - Blog: http://computinged.wordpress.com

Oh sorry, forgot to add that bit. I am on Windows 10, and the latest version of JES.

Disconnect with Java sounds likely, I very well may have installed a new version of java in the past month. How would I remedy that?

What I can give is that the jes.bat file outputs this before crashing:

Welp, I've managed to get it to work by getting the java-included .zip file.

That's great to hear! Thanks for letting me know. Yes, my guess is that you ended up upgrading to a version of Java that's incompatible with Jython. - Mark
