Hi there,
I upgraded my Windows 10 to Windows 11, then immediately installed Processing 4.3.1 for Windows.
Windows 11 did not let me even download it (i had to turn off Antivirus).
Once I managed to prevent Windows from deleting the file, it would not let me execute processing because it detected core/library/core.jar as a “TrojanDownloader”, saying something like “This software is dangerous and downloads other software”. I had to also manually unblock it.
Just saying in case someone else has the same problem. It can be fixed by manually and temporarily switching off Windows security or creating exceptions.
Best!
Luis.
