I just downloaded processing and the program doesn’t launch. I read through [this page](https://processing.org/tutorials/gettingstarted/) and it seems like I should be able to just download the file, extract it and run the .exe, However when I do so, I get the loading screen for a fraction of a second before the program crashes. I also read through [here](https://github.com/processing/processing/wiki/Troubleshooting) and ran it through cmd with --l4j-debug, Here’s the output, but I don’t know what to make of this

I never installed or reinstalled java, I read on one of the processing pages that

> It’s never necessary to install Java to use Processing. Across all platforms, Processing uses its own copy of Java that’s embedded inside the application.

I’m kinda at a loss as to what to do

`javaw.exe (not found)` Ru sure you properly extracted the downloaded “.zip” file? 🤔

Maybe use a better utility for it like 7-zip? 🛠 [https://www.7-zip.org/](https://www.7-zip.org/)

Huh, That was it, I hadn’t checked before but the extracted file was 1.95 Mb, little small since the download was 120Mb, but once I used 7-zip it extracted correctly and worked.
