I am having an issue right now where I am attempting to export my sketch in python mode as a windows application, but processing is consistently giving me the same error, no matter what sketch I try to export. It does generate two folders, application.windows32 and application.windows64, which have java, lib, and source folders in them, but no exe or anything I can run besides the original pyde file I used to export, residing in the source folder.

This is the error:

java.io.IOException: Launch4j seems to have failed.

When I was trying to debug and look this up, I ended up looking in the modes folder in processing 3.5.4, and there was no python folder in it, it was just java. I don’t know if this has to do with it, but it might. I do have python mode installed however. I’m happy to provide any other information about the issue if it’s needed. Any help is appreciated, thanks!
