Unable to open Processing

Hello all. I recently downloaded Processing. However, every time I open it, I get this error:

Does anybody know what this error means and how to fix it?

there was a similar report already.
usually we not “install” ( better UNZIP )
the downloaded processing to windows system.

try unzip to …/Documents/
so you have

c:/Users/ < user > /Documents/processing-3.5.4/

and after start processing creates “sketchbook” at

c:/Users/ < user > /Documents/Processing/

and also “processing ?system dir?”

c:/Users/ < user > /AppData/Roaming/Processing/
