Please provide more detail. The situation sounds like you are downloading the 64bit Processing and then trying to run that version on 32bit windows. This will not work. Not enough bits. :)
Direct downloads for Processing 3.2.1 -- both Win 32 and Win 64 etc -- are available from the Processing download page.

I mean P5.js. I downloaded the windows version from here: http://p5js.org/download/
and when i try to install it it says my version of windows is wrong.
(Mod edit: fixed category and subject line to clarify that 'it' is p5.js)
Where can i get the correct version for 32 bit Windows 7?
There is no 32 bit version.
But note that you don't need the editor to use P5.js. You can just use any JavaScript or basic text editor.
