Java error on startup when I launch Processing

hi there,
i want to help, but also i have problems to understand your report.

-a- second post first:

no idea what you talk about

  • install ( unzip ) processing
  • copy one of your sketch

anyhow miss the info how it play out.


first post:

ok, with processing we must consider 3 locations on your computer:

C:\Users\ < USER > \Documents\processing-3.5.3

when you start we talk about the

C:\Users\ < USER > \Documents\processing-3.5.3\processing.exe

( or any link to it )

  • -b- at first start it makes 2 more directories

C:\Users\ < USER > \Documents\Processing\

what is for sketches, libraries and modes
called sketchbook
if you deleted that you lost all your projects.

  • -c- and a directory i call system directory ( here for windows )

c:\Users\ < USER > \AppData\Roaming\Processing\

where the preference file and old error logs are.


in case if unzip newest downloaded processing for your system
and still not start, i recommend to delete that -c- system directory
possible there is something bad.
what you can loose max with deleting that is any adjustments made in
PDE / File / Preferences /
( like skechbook path and editor look… )


try to be more precise next time.

  • OS name and version
  • processing version ( and bit 32/64? )
  • downloaded filename
  • path information
