I am trying to install and run the **Processing 4.0b8-Linux-arm64** on my **Raspberry Pi 4 Model B with 1.5GHz 64-bit quad-core ARMv8 CPU**. After downloading the package from the Processing download page, I extracted everything from the package and got the Processing icon on my desktop. But When I click the icon to open the program, there is no Processing open. I also tried to open it from the main Raspberry dropdown menu \> programming \> Processing and Processing folder \> Processing. None of them works. Does anyone have the same issue before, and how did you fix the problem?

Thanks for your help ahead.

Hello hyang,

take a look into your package directory.  
See my directory below.  
Check permissions and owner first and check for all files marekd as executable.  
Do you launch sudo ./install.sh

If everything else fail, try ./processing  
and check any error messages. At least in /var/log/messages(?).

Hope that give you an idea where to look for.  
And check which processing you are using.

I’m on a 64-bit OS

So in case you are on a 32-bit OS use the 32-bit package of processing.

Thank you, Tom. I got the Processing running now. Your advice and information are very helpful. I made a mistake in installing the OS 32-bit on my Raspberry Pi. That’s not compatible with the 64-bit Processing package.

Thank you again!
