Processing IDE won't start

edited January 2016 in Using Processing

Hi, It happened yesterday, at 1pm it was working and at 6pm didn't. I don't remember changing anything. I just know that processing IDE starts but the process javaw.exe disapears from taskmanager and nothing more happens. I searched the web and tryed some things but nothing works. Please help, I need it for class..

    It's a shot in the dark. But how about using a cleaning program such as CCleaner to remove any trash from Windows; including registry as well? b-(

    Another option is use a virtual machine emulator like VirtualBox. And install a Windows or even a Linux in it. Then install Processing in that clean-slated OS. ~O)

  • You could try System Restore to restore Windows to a point before 1pm yesterday.

  • Try deleting the folder where your preferences.txt file is. It works for some people. Perhaps do a backup before, in case you want to restore some settings.

  • Have you read the Troubleshooting notes?

  • Thanks for the replies, I got it, I deleted processing folder from appData and restart computer. I have tryed before delete the processing files from appData but nothing changed.

    Thanks ;)

  • I just added a new description to the Troubleshooting page to help clarify:
