Hey, i wanted to play around with processing but i cant seem to get it working. These are some things i found out:

1. when i launch processing for the first time it starts up but if i try to run some code it crashes
2. if i try to launch processing after that it shows starting screen for few seconds and then nothing happens, all i get is stuck java process that i have to end manually
3. if i delete Processing folder in AppData i get to point 1. processing starts up, but crashes after i try to run anything

when i tried to run processing in my clean win10 VM everything worked ok, but i dont really want to use my VM just to run processing.

Could you give us more details about your environment?

Sure, im running Win 10 Enterprise edition 64 bit, i have JDK 1.8.0\_131 installed if that means anything, also my JAVA\_HOME is correctly set to the location of my JDK. But from what i can see processing uses its own versin of java to run. I dont really know what else to post other than my operating system version.

I thought i could find something in Processing/console folder in AppData but bot .err and .out files are empty

Besides the usual “Uninstall reinstall” suggestion, I have to admit I’m just as lost.

However, if you’re main goal is to quickly run some code you’ve stumbled upon (and you have wifi), I’ve found [openprocessing](https://www.openprocessing.org/) quite handy. Really depends on your use case.

Can you open Processing.exe from the command line? (Shift+click in the explorer window then click open command prompt here)

If there is a crash there should be a stack trace with maybe some more information…

I experienced something similar. Processing 3.4 on Win7 worked in the morning; in the afternoon, the About panel appeared for some seconds, then Processing crashed. I didn’t get any error messages when launching Processing from the command line.

Turns out I simply had not enough memory (\< 1.5 GB) on my hard drive left! I freed up about 8 GB, now Processing is working again. Guess the Java VM tries to allocate some (huge) amount of memory up front, and sillently crashes when it can’t.

Hi. I am using Processing 3.4 on Windows 7. Same issue occurred with me as well. I cleared 11 GB. But I am getting the same thing. The software just opens for few seconds and crashes before the editor opens. I am completely stuck now. ☹
