How to Properly Install Processing 4 on Windows 10 and Remove “Search for App in App Store Prompt”?

The function addColumn(String) does not exist

Mac is the only Processing version w/ an actual install, which the OS recognizes as registered. Both Windows & Linux versions are presented in a standalone compressed file. We need to decide the place where Processing’s extracted folder goes into. My advise is to pick an unguarded non-system path, like “Documents”, to extract Processing into.

Problem when updating libraries

Just a guess: you could try out v3.4 just for updating libraries: Download.Processing.org/processing-3.4-windows64.zip Also consider uncompressing the “processing-3.4-windows64.zip” in your “%HOMEPATH%\Documents” folder or some other place away from the OS’s system folders.
